2020 Supra Audio FULL BUILD for SEMA!

[Music] this is the 2020 Supra and this is my take on a custom car audio build but way way way rewind who is this car for how did this project come about and how did I design this project what were the steps for building and where is this super going my friends it's time for the full super build blog so here's the deal about a month ago I got an interesting phone call from these guys right here JL Audio and they had an interesting project that they were working on for SEMA where they were collaborating with another youtuber the project vehicle a 2020 Toyota Supra now if you have followed my channel since the beginning you know that I didn't just one day wake up and get out of bed and build like I do now this channel has been a documentary of my growth and while I used to use a router on the ground and used washers as templates things have definitely changed now there are two reasons that I'm even mentioning this reason number one this is my first time having a build in a booth at SEMA it's a bit of a milestone and I'm pretty excited about it and the second reason that I mentioned this is I went from having no experience whatsoever and hand-me-down tools to developing my craft into what it has become today and there's no reason that you can't - I remember looking at SEMA builds and wondering if I could one day be a part of something like that so I'm just hoping that I can maybe even inspire just one of you guys out there to tell you you can do this and that my friends is why I jumped at this opportunity to help with this build now let's talk details because there are a lot of moving parts here with this collaboration on this project since I am focusing on the fabrication of the amplifier rack and the subwoofer enclosure I've teamed up with a shop called sounds plus as they will do the wiring of the speakers and amplifier and tuning of the complete system now the owners of the super are Kevin and Brittany of lite-brite studios that's the name their YouTube channel they're both avid car enthusiasts and they actually had me on a video on their channel more on this later finally we of course worked with the awesome folks over at JL Audio who sponsored this build and provided all of the gear now a bit of a side note this is a long video because it's going to cover the entire build and you guys know that I'm long-winded I like to explain everything so to help you out I put some timestamps down in the video description so you can check out different sections of this video my first step on this project the first thing I had to do I got a ton of pictures of the car and some basic measurements allowing me to come up with a plan alright guys so let's talk about this design for a project like this that is for a show car where there's multiple sponsors involved where there's different parties actually working on the vehicle where I won't have a ton of time with the vehicle itself I think it's really important to come up with an actual design this design could be as simple as sketches on paper or we could even go to this level right here where we use computer-aided design I want to talk about what I came up with for this design and what the overall plan is with you guys so you can follow along first off let's talk about our subwoofer enclosure here so this is going to feature a jail audio ten tw3 which is a shallow mount subwoofer because one of the main design goals behind this system was to keep the subwoofer enclosure as small as possible and also to allow it to be removable now the other thing I want to talk about with you guys is this right here design inspiration design elements and this will give you an idea how I came up with a lot of the design and shapes for this build what I have here on screen is a picture of the door panel on this vehicle and you can see that there's a lot of really hard lines like straight line here straight line here which is kind of different because the Supra itself actually has a pretty curvaceous exterior but on the inside of this again hard line hard line hard line and you can see that these hard lines are met in the corners here with kind of a smooth radius so keep that in mind the other thing I want to call your attention to is look at this tweeter right here on the door panel you can see it has this shape it's kind of a circle and then it's got like this extended section that comes out of it so straight design elements and that extended circle you can see that I carried both of those over into this enclosure we've got this straight design elements here that have the radiused corner and then we also have that extended circle on this case I wanted it to be on each side to give it some symmetry around the subwoofer for this front corner of the enclosure I didn't want it to have a hard sharp corner like a normal enclosure would so I'm actually going to be curving the wood to bend it over the front of the box some other design elements in the corners here just to give it a little bit more of an interesting look and then I've got these wings modeled in these aren't exactly to scale yet these are just a concept but the idea is that these are going to be able to be removed with magnets once removed it gives us access to a mounting bracket that is going to allow this enclosure to bolt into the vehicle this is actually really critical to the owner of this vehicle they wanted to be able to remove the enclosure really quickly if need be when they're taking this vehicle to the track so that they can enjoy it the other design element I want to talk about is on the dash here you can see that there's some carbon inserts going on in the dash along with red accents so keep that in mind that's because on the enclosure itself I'm going to have these red accents made out of acrylic going around the outside of the subwoofer and then on the amplifier rack cover a similar thing we've got these red accents around the amplifier and around these two inserts here that cover the factory mid bass woofers so this is the area that everything is going in you can see those two factory woofers that we're going to be covering up with the amplifier rack beauty panel the amplifier is going to be in the middle and then the subwoofer enclosure right here now why am I not doing a fully-formed subwoofer enclosure that matches the sides and everything because we need to be able to get this enclosure easily in and out of the vehicle again the design intent is for the enclosure to be easily removed and then that amplifier rack is obviously going to stay in there the amps gonna stay in there because it's going to be powering all of the component speakers we'll be talking more about the speakers that are planned for this build let's talk a little bit about the amplifier as far as the design goes on this amplifier rack again notice that we have hard with these rounded corners and then again here's that circle with the extension coming out of it in my design again I had to consider how is this actually going to mount into the vehicle so what I'm going to be doing is will be coming up with a bracket system that will sit underneath this piece and be hidden and in order to access it will remove this amp insert in the middle here which will give us access to a couple different bolt locations that will hold this whole assembly in the vehicle I have some cool ideas for how that inserts gonna hold in place and how everything is going to come together you guys got to stay tuned and keep watching through the build here after I had the final design I went ahead and I applied some different materials just to get an idea what this is going to look like when finished so we're gonna have some vinyl materials wrapped on this part here we'll have a vinyl insert we're going to do carpet trunk liner on the subwoofer enclosure again of course we have those red inserts and then I even added in it's kind of hard to see in this picture because it's low resolution but there is the carbon fiber inserts here so just giving myself some of the overall dimensions that I need to start cutting out this enclosure something I do want to point out here though is it's taking me years and years to get to this level where I'm actually designing everything and modeling it beforehand and coming up with a plan like this I don't want you to get discouraged because you don't know how to design on a program like this that's not what's important what I am stressing is important is you have to have a plan the plan can be as simple as just sketching something out on paper with pencil trust me having a plan ahead of time will make a huge huge difference I'm done talking let's get into this [Music] [Music] now that I've got the top baffle with the cutout hole for the subwoofer and you'll notice that I made sure I left enough distance to wrap around the front of the enclosure I need to do what is called kerfing so I made a little practice piece here just because I wanted to test my cuts before I accidentally messed that piece up but what kerfing is is I'm the saw I basically cut through all but just a little bit of material I leave about a little less than the sixteenth of an inch I make a series of cuts that are lined up with where this curve will be on the enclosure and that allows me to actually curve this around the front of the box my test piece worked out good it's gonna be a nice flowing curve let's get it made [Music] so now that I have the enclosure itself fully built with this nice curved flowing edge in the front I need to do some of the detail work on top now for that detail work you're gonna see me using several different specialized tools from mobile solutions these different templates and tools allow me to actually create these shapes I'm going to kick it off with the smart ruler which allows me to sketch a grid on top of my piece that I'm going to be converting into a template shape with this grid from the smart ruler allows me to do is quickly create shape geometry without messing around with constantly measuring with a tape measure for example let's say that I want to make this line right here what I do is I can count over a certain number of squares on this side from my center line and make a mark I count over a certain number of squares and a half to this side make a mark and same for these two points here now I can connect those points using a straight edge on each side so now I have that perfect line on each side of the shape perfectly symmetrical I'm going to repeat this process for all of these different lines now again because I had a computer model is able to take all the dimensions I needed in order to start creating this shape but if you didn't have the CAD model you could actually literally use graph paper like this you could draw out your shape and then just scale it up now that I have all my lines sketched out I need to start adding the radiuses into the corners so I'll do that with just using some of these circle templates again you can use literally anything that you have on hand in the early days of mr. old car audio fabrication this was even the template right here you would just take the top of a spray paint can and sketch your line so now that I have my shape completely sketched out I need to start trimming it on the router to do this I start with a straight edge and I use template tape to stick it onto my board next I'm using a spiral flush trim bit that has a bearing on top that will ride against the template in order to trim that wood below to the template shape so now I can move on to doing this part a circle cut and I want to make sure when I'm doing this circle cut as soon as I get to this straight part of the cut that I stop my cut so then I can follow up with sticking this on again and continuing that process and I'm going to repeat this process several times let's knock it out there Wham and there we have it completely have made my shape so now we have our first shape here and next I want to show you how do we create the male shape that's going to sit inside here using this existing geometry now I do want to point out that throughout the rest of this video whenever I'm creating a shape this is the process for doing it I'm probably not going to show it throughout the rest of the video just because it is time-consuming but now you guys know let's make this male shape inside here to get this process started I take a piece of scrap wood and I take my master template and I've stuck it on here you can see the two are stuck together and stuck it together with template tape and I also drilled a small quarter inch hole we've got the quarter inch spiral flush trim bit here in the router and that hole is so that I can insert it through the wood so I've got the router bit there everything is currently off I'm going to get the camera set up because I need two hands on the part for doing this but what I'm going to do is I'm going to hold this steady I'm going to turn on the power and make sure I'm still pressing against the bearing and then I'm gonna carefully trim this out making sure that I maintain contact with the bearing with this shape the whole way around so after doing those steps now have this perfect mail piece that fits right in here now if I did want to decrease the size of this gap between the two pieces because right now it's a quarter inch for that bit I can do so the way I'll do this is I'll take this piece and I'll stick it to a new piece of material that is larger and then I'll use a flush trim bit that has an oversized bearing on it like this that way when the bearing rides against our existing piece of material it's going to cut the new piece of material to be larger in the meantime I use this same technique to create these corner pieces that go up here you can repeat that process off your existing master template so shape wise I have everything I need now I'm going to make a cutout in this piece for the subwoofer of course and then I'm going to transfer this shape to a thicker piece of material and I'll transfer this shape to just to have a nice clean piece so like I said I've repeated the shape making steps in order to make these other pieces you'll notice that I increase the gap size here so that this is completely flush I transfer this to half-inch material as well as this and then this is my new quarter inch piece here and I know that I want this gap to be precise because I'm going to transition from carpet to vinyl so I have a nice eighth inch gap in between here again I controlled that gap size with the oversized bearing let's talk about the plan moving forward these pieces here are going to be permanently attached to the enclosure they're actually going to be wrapped underneath the carpet they're just there to give the enclosure some extra shape and then this insert will be wrapped separately and be removable now since these pieces here are gonna be wrapped with the carpet material together I don't want these like hard steps I want to add some champers to these pieces so let's start with adding a chamfer to this piece this is what the chamfer bit looks like you can see this is a 45 degree chamfer on this piece of the edge I'm gonna be chamfering is right here and I want to maximize the height of that cut so in other words if we look at it from an angle right here I want the top of this cutting flute to be even with this top surface but if I do that it doesn't leave anything for the bearing to actually ride against so really quick I'm gonna flush trim another copy of this so that I can fully maximize that chamfer and then I'm going to make that cut and here we have it see how much of a difference it makes adding that chamfer to that edge it's going to look super cool nice and slick underneath the carpet I'm going to do the same thing to this piece here this piece here and this piece here but on these since they're thicker I'm only going to chamfer it down to this surface I only have to chamfer a quarter of an inch and these are half inches so there's plenty of material for that bearing to ride against so you can see how those chamfers are looking now I want to add a round over to the outside edge in the inside edge this is what a round over bit looks like it adds a rounded profile with those round overs added you can see how doing this detail work really brings these shapes alive and adds a ton of depth and dimension to the panel now I did a light round over on this edge as well as this corner here just would give everything kind of a flowing look before I attach those pieces to the enclosure I still need to make my round over around this edge here now because I curved this and filled it up with the sawdust and glue I'm fully expecting it to kind of potentially break up a little bit when I come over with the round over a bit if it does I'll just clean it up with body filler no big deal hopefully it will hold solid but yeah we definitely need to add some round over to this panel here to give it that shape and I'm gonna make marks here so I know where to stop my router bit because obviously I don't want the round over to continue under these pieces and here we have it after adding that nice round over to the edge I definitely feel like that gives it a lot more of a finished look I love this curve on the front here really has and that nice blend of being curvy yet having these hard straight lines like we talked about in incorporating some of the other design intent from the vehicle so I've got the Box completely built still need to do the upholstery process but I got word earlier today from Marty over it sounds plus the shop that I'm collaborating on this build with that all the jail product has arrived let's head on in and check it out that's right the gear has a rod so I've got it all laid out on the table here let's go through each of the different components so that's going to be used and let's start with the speaker's here so here is a c5 component tweeter this is a three-quarter inch tweeter so part of this component set right here is the c5 four inch component so these will be going into the front of the vehicle nice and beefy looking good and then of course the speakers and the subwoofer are going to be powered by the amplifier here this has a DSP built in so that they can integrate with the factory audio system take the signal out of the factory audio system and do the tuning with the time alignment equalization crossover control the little logo here actually comes separately which is nice so depending on the install we can angle the amplifier in different directions and then mount the logo in place for our application it's going to be like this sitting between those two OEM woofers underneath the amplifier rack and then finally since we needed a nice shallow subwoofer we're using the jail audio 10 tw3 I know it's kind of hard to see on camera here but if I check on my ruler and measure the mounting depth it's a little over three and a quarters inch for the mounting depth so we can fit this into an enclosure really easily with shallow mount if we look at the back of the subwoofer you'll notice that there's no hole here into the magnet to cool the voice coil assembly that is by design that way we can have this being nice and close to the inside of the enclosure and here's some nice beauty shots you can see the spider here the voice coil is down inside dual voice coil of course so you get the four connections and the subwoofer is not only designed to fit in a shallow mounting depth it's also designed to use really really small airspace I believe we talked about it earlier in the video this is just over half of a cube of sealed airspace that this is going to be going into so Marty and his team here it sounds plus we'll be doing the installation of all the wiring of the component speakers they'll be doing the wiring for the amplifier and then obviously as you've seen earlier in the video I'm making the subwoofer enclosure for this bad boy right here the next step is to get started on the amplifier rack Marty's been working out a little something over here this is Marty owner of sounds plus so unfortunately the car is currently over at the performance shop but hopefully it'll be here soon let's go let's go so now that we have received the gear and I have access to it I can check the fitment on the subwoofer enclosure here in the amplifier rack you can see the sub is good to go here and I did a couple of other things in the meantime obviously we need to bolt the subwoofer to the enclosure so I added these threaded inserts I like using thread inserts instead of just simple wood screws because this way I can take the subwoofer in and out multiple times if need be without degrading the quality of the hole you can see I've also made this acrylic insert the acrylic insert actually press fits into the back of this piece that we created earlier and in order to create that press fit gap what I did is I used that rabbeting bit that showed you guys this creates a precision notch in the piece so there we go we have our press fit in acrylic now also in the meantime I use those same shape creation techniques to create all the different shapes for the amplifier rack one thing that did end up coming up is rather than having the amplifier along the centerline between the two speakers I did actually have to shift it over and that's just to allow more room for the wiring that comes out of the amplifier the amplifier will be sitting here and the wires will actually come out this direction jail audio also sent over these these are actually the grilles from some of their 8 inch subwoofers and I wanted to incorporate them into this beauty panel to sit over those om woofers so what I did is I precision cut out this hole so that is the exact OD of these grilles I have a little note for myself because I'll have to make this hole a little bit larger to allow for the vinyl clearance when I go to wrap these but you can see that that press fits in there as well and all of this is going to start to come together the guys over at sounds plus are going to be doing the actual amplifier install and bolting it into the vehicle so I made this template for them that they can easily put in the back of the vehicle with the to OEM speakers and it will allow them to perfectly line up where they need the amplifier to go now I do still have some shaping that I need to do on these pieces with the different router bits so I'm going to start with adding a round over to this piece which is permanently attached to the base board I'm going to go the round over starting here all the way around this profile so I've rounded over this edge and made it smooth and while I still have that round over bit loaded in I'm also gonna do the round overs on these inserts I'm gonna go all the way around the outside around the inside of the speaker hole and around the inside of this insert so that gives us these now I'm this piece I need to add a 45 degree chamfer this is going to be permanently attached and it's just going to be wrapped under the vinyl and there we have a guy's got that chamfer added there I also off-camera added a round over on the top edge here now I can permanently attach this piece using some CA glue to the rest of the assembly and then I have each of my inserts that will pull out everything's gapped I've now also added these carbon inserts along with the acrylic red insert I made sure to match the grain so it's going kind of the same angle on each side and then I also have that acrylic red trim in there and then I back-loaded both pieces just using a rabbeting bit into the back of the piece with this middle insert here there's an interesting design challenge because I need to be able to easily remove it so that if we need to access the amplifier I can actually remove this full assembly from the vehicle this full assembly is going to be bolted down in this location and I don't want to show the bolts so I need a way to remove this access panel and to hold it on I'm gonna be using magnets these are neo DNA and magnets they are extremely strong and I have this Forstner bit right here these are 3/8 inch in diameter so I'm gonna use a 3/8 inch Forstner bit to make holes in both this and this panel and then I'll push the magnets into each of those holes and adhere them in that hole with CA glue now that all the magnets are added you can see that this piece has a satisfying click perfectly into place and then if I need to remove it it's on there nice and strong but if you pull just right it comes right out I can now get started with the upholstery process I have this nice factory match material here this vinyl I'm going to be wrapping this insert first in order to do this I spray both the piece and the material with contact adhesive and allow that contact adhesive to dry this is key for the upholstery process you want it to be dry to the touch once it is I will start to wrap the two pieces together the outside of this shape here press fits into another piece so I can just trim it flush with the back but for the inside of this shape I'm going to trim the material and then I'm going to tuck the edge into a rabbeted groove created on the back the rabbity groove gives me a perfect guide to make a cut using my razor which gives the backside of this panel a nice finished look and with this we have our finished vinyl wrapped piece and this process is the same for all of the vinyl wrapped pieces throughout this project next I needed to do the carpet wrapping process on the subwoofer enclosure of course I do the same thing here where I applied the contact adhesive to both the subwoofer enclosure and the carpet but I do have a trick up my sleeve that I like to do for tucking the edges of the carpet to hide the transitions you may remember earlier in the video during the woodworking process I added a little notched cut into the corner of the side pieces I do this on purpose because it gives me this little groove here that I can tuck the carpet into I can also use the edge of my shape that I added to the top of the box to trim the carpet there too as that's where the vinyl transition will start got all the polyfill in our insert is completely attached with that red trim time to get this subwoofer wired and installed and just so you guys know I of course have some Farrell's on here in order to go into the wire terminals on the subwoofer and then I made myself a little quick disconnect plugs this box can be easily removed out of the vehicle to mount the subwoofer I'm using those threaded inserts that I showed earlier along with some machine screws alright the moment we've been waiting for I can officially remove the protective cover here and there it is our finished custom subwoofer enclosure for the Supra I am really really happy with the way this turned out I'm pretty excited I think the the client is gonna be pretty excited I think JL Audio is gonna think this is super cool I love how these lines turned out right here I think everything kind of blends well I didn't up making a design decision to switch up to adding some wing covers on the outside here the bracket is actually gonna come off the back of the box on each side and then these separate pieces are going to be what magnets into place over the bracket to hide it and then you can just remove them in order to access it to remove it we'll see more on that in a little bit I took the time to clock and orient each of these bolts exactly the same we want this to look perfect showcar quality what do you guys think now off-camera in the meantime I've also finished wrapping this right here here is the completed impractical with our grills over the OEM speakers I wrapped this in that same upholstery vinyl that's on the subwoofer enclosure I have these nice red accents you can see there's the carbon insert I really love how this geometry turned out here with the different lines we've got some of the jail audio.speaker girls here from some of their 8 inch subwoofers that I incorporated into the design I've got the trim around that the amplifier this is probably one of my favorite builds to date if you take a look at these corners here these corners are really challenging to do because they're so tight and they are looking flawless perfect wrap there with the vinyl and don't forget everything is serviceable too so if I need to access my mounting hardware which will go up here in order to remove this from the vehicle easy to do so and then with the magnets just clicks right back in place so my friends we've got all the parts built let's get them shipped over to sounds plus so that they can bolt them in and we can check out the final install [Music] [Music] [Music] [Music] so here is the finished supera install start with taking a look at the custom subwoofer enclosure you can see that this houses the 10 tw3 from jl audio and a shallow mount subwoofer configuration this shape on the top of the subwoofer enclosure matches the door panels like we talked about in the design phase it also has this red accent that matches the interior of the vehicle along with the same upholstery vinyl on the insert piece and Brad let's talk about those panels that are on magnets you can easily remove this out here's access to the hex wrench that we can use in order to get the allen key out to take the box out next up we have the amplifier rack beauty panel the amp rack BD panel covers the jl audio VX 800 / 8i DSP integrated amplifier and on each side of the beauty panel are the OEM midbass speakers again i made sure that i match the interior with the red accents and this piece also incorporates some carbon fiber inserts up front here in the Supra we've got the four inch c 5 component speaker along with the tweeter you can see that we also made some JL Audio badges for the tweeter the team here at sounds + mounted the control knob for the amplifier in this convenient location right here it has two different dials so we can control volume and we can control the subwoofer level on the bottom now overall the final system sound oh yeah for being such a small subwoofer the bass is really really impressive and with the tuning of the amplifier crystal clear mids and highs now heaven of brittany won't actually see the Supra until it arrives at SEMA so I can't wait to hear what they have to say when they see it I was able to meet them though as they visited sounds plus and together we shot a video talking about the overall design for the vehicle and why we were going to do some of the things the way we did them so if you guys want to check out that video I'll put a link down below a big THANK YOU to Marty and the guys over at sounds plus for teaming up with me on this build and of course a JL Audio for sponsoring the build and providing all of the gear I still can't get over the bass output from this slim tw3 if you guys want to learn more about this subwoofer check out a local jail Oh dealer or you can visit the link down in the description now if you want to see the build in person it's going to be in the mile star tires booth at SEMA and guys I would love if you could take a picture of it or with it and post it on Instagram and tag me at car audio fab that would be awesome finally a big THANK YOU to you you guys out there watching these videos helping me continue to push on my passion to helping others learning how to master car audio I love you guys keep rocking it I hope to see you in an upcoming video don't forget to design build and install
