DIY BOSE Subwoofer Repurpose / Rebuild

[Music] hi guys so I'm gonna go ahead and do a video today on repurposing a Bose subwoofer and what I got here I've got the Bose acoustic mass 6 series 2 subwoofer I did some Craigslist shopping the other day and I found this bad boy for 20 bucks so without all of the stuff that hooks into it the satellites and all that stuff this thing is basically not worth a whole lot and it's not a bad subwoofer they make decent stuff it's just that what do you do with this thing after it's been a little beat up and it's got some damage and nobody loves that loves this anymore but we're gonna try and give it some love so what I want to do is I want to repurpose this thing I'm gonna take the skin off and try and redo that I've never done that before so that'll be something new for me to do we're gonna take this thing apart back here we're going to take the electronics out of it so that we just have a raw subwoofer here and then I went to one of my favorite places parts Express and I got myself a 2.1 channel amplifier so let's go ahead and open all this stuff up get it ready to go take a look inside this guy see what it looks like inside and we'll get ready to see if we can properly repurpose this thing and make it into something cool okay so let's get at this thing here we're gonna take these little screws off and see what's inside here see what mr. Bo's made this thing out of go pop this guy open and see what we see like a circuit board in there I've got a couple of plugs take those off all right well this is an unpowered unit so all of this gets its power off of whatever signal the speakers are sending it so inside here we have one visible woofer and then there's a port inside here for the sound chamber and these appear to be dual voice coil this woofer is a dual voice coil because there's there's a set of pins on one side and then there's a set of pins on the other side that's why we got four wires here so this is a likely a2 speaker system and this is probably the same thing we'll have to do a little research on that and figure out what the wires do which ones do which and we do have a positive and negative indication on there so that's good all right so now we know what we got to deal with okay so now that we got this opened up we know what's inside the hole let's go ahead and unbox our Dayton audio parts Express 2.1 channel Class D plate amplifier now this I bought this because it's this was made to go on a subwoofer kit so what we got inside here is I guess everybody on YouTube does that so get rid of the instructions we've got a power cord and then here's the money right here that played amplifier so so what we got here from parts Express is this plate amplifier it's got two times 22 watts output for satellite speakers or for desktop speakers and it's got the point one is the woofer output so it actually has two sets of amplifiers on here it'll power the speaker's and internally like I said this is me to go on the back of a subwoofer kit box so this is the output for the subwoofer and these are the outputs for the two left and right channel speakers that we're gonna hook up on my desk later on when we get this all done and it's got an inputs for either RCA or mini jack 3.5 millimeter mini jack it's got on/off auto switches to it bass boost volume for the satellite speakers subwoofer volume and it's got the sub frequency which is great because this way if we're using small speakers we can use this frequency cutoff to adjust where the sub comes in and it will automatically take care of the crossover for me so I'm looking forward to that it's a nice little unit and it was 65 bucks so pretty cheap definitely for basically well 65 plus the $20 I spent on our subwoofer 85 bucks not bad for what might be a really good subwoofer so let's go ahead and make sure this thing is going to fit let's take a look at this so looking at the hole that's already in the subwoofer we're gonna have to make it a tiny bit wider and certainly longer but I mean looking at this on the back here I think this is gonna look pretty darn cool so let's take a look what do you think that'll be pretty nice so all right well let's get let's get to work on taking this thing apart see if we can see if we can make this hole bigger alright so because the front of this Bo's is in actually pretty good shape I'm gonna go ahead and and mask this off with some just some some masking tapes so the one we're working on this it'll protect the front a little bit I don't want to have to do any more work than I have to on this thing it looks like just the sides and the bottom are peeling off and I've got some new melamine that we're gonna put on it so we'll come back to that in a little bit but I'm gonna go ahead and mask this off and see if we can't protect the front of this thing a little bit which will make less work for us down the road so peel this stuff off on here I'll just trim it up when we're all done all right come back to this in just a minute okay so I've got the front all masked off so that's protected his best we can I'm not expecting miracles from it but the next thing I want to do is I want to try and get some of this old melamine off this cabinet because it's just peeling off anyway it's just going to get worse if I if the melamine doesn't work out the stuff that I bought I'm just gonna paint this thing black with just paint so again it's gonna be under my desk repurposing a twenty dollar subwoofer so not expecting great miracles out of this so it looks like they wrapped this on three sides with this stuff so I think we can just kind of get at it here and peel it off the glue is so old on this it should just just come at it like this so we'll come back to this when it's all peeled off because this is gonna take a couple minutes okay so we got all the melamine off boxes now just plain wood except for the front that's mask let's get these little feet off here let's see if we can get these guys off easily and try and pop these guys out and it looks like they're just stuck in there so they come right out I want to use those later so the next thing we're gonna do again I don't want to get a bunch of dust and sawdust and stuff down inside the box so we're just gonna take a piece of plastic from a plastic bag I'm gonna stick that down inside here and try and keep the sawdust from getting all over our stuff a little easier to clean up that way so there's that all right so remember those instructions that I threw away well we need to know what size hole to cut this out at and it just happens to say in the specifications that the required opening for this is nine and a quarter by four and five eighths so guess what the opening is exactly four and a half inches so it's one eighth of an inch too small and then we got to go out to nine and a half so we'll do some quick measurements here make some lines and then we'll get to cutting this thing okay okay so let's do our measurements now we'll draw a line across here at nine and a quarter and we're gonna come off of this just a little bit wider I'm probably going to end up enlarging that hole because it's probably not gonna fit just right unless we go a little bigger so but I think maybe what we'll do is time lapse this and then you'll be able to watch the whole thing and you won't have to listen to me for the whole thing so let's go ahead and set some time-lapse up and we'll get whole cut out [Music] okay so use the dremel tool for part of it got got a good score on it so it's a nice thing cut I ended up having to use a saw cuz the Dremel didn't go deep enough plus was making a lot of smoke as you could see and then I went ahead and finished it off with just a sanding wheel on the Dremel just to kind of give it a little bit cleaner edge it's not perfect but nobody's ever going to see it it's gonna cover it up with the subwoofer so I'm gonna get a vacuum cleaner and clean this up a little bit and get the plastic out and then we can test fit it and see if we need to cut any more maybe I should test fit it first let's test it real quick test fit complete she fits alright we'll clean this up okay we're to the point now where we need to sand the outside of the box get it as smooth as possible cleaned up and then we're gonna put the melamine on it so and I've never done the melamine before so I've no idea whether it's going to work like I said if that doesn't work we'll fall back to paint so I've got my sander ready to go I've got 120 grit on here first and then 220 after that that should be sufficient to get this smooth enough and then we'll get mom's ire and fired up and get ready to put the melamine on here and see how that works out so I guess let's get sanding [Music] okay so now let's go just take some alcohol and we're gonna just get the rest of the dust off this get the best adhesion we can I'm not using a ton I'm just just getting the dust off this melamine stuff is likely gonna stick really hardcore it's got a ton of glue on the back of it so it should be pretty good to go with this again we're not looking for miracles we just want to get it cleaned up a bit alright that up alright melamine how do we do melamine so I've got some pieces of this called bandit melamine or a bandit veneer facing and I've just cut it oversize so I can trim it out and I've got enough pieces to do top bottom back and each side here as you can see so I think what we'll do is we'll start with maybe the bottom do the bottom and then trim it up and then we'll do the two sides and then we'll put the top on last so this would be the bottom here so we'll take this and since I got a straight edge on here already I think we're gonna try and use that like that alright well here there's nothing parchment paper put parchment tape paper down before you put the iron on it all right so my iron has been warming up for about 10-15 minutes and it's set for cotton which is what they recommend it's about 400 degrees and it's hot I mean if I touch this it's really really really hot I have no idea how long to burnish it on but we're gonna find out here in just a second Harley it's really hot like burning my fingers hot all right so then we take roller okay so learning that working with melamine sucks if you've never done this before it's there's a bit of a learning curve so we we stopped the camera and learned a little bit and then I don't know I suppose it's okay you run this little cutter along the edge and it's supposed to trim it right off but it doesn't get it like perfectly flush which is a problem because the next piece is going to go on it's going to hit this little lip right here so we're taking a razor blade and we're just gonna do our best to try and trim this up which is really a pain this is certainly DIY they end up on the editing floor so we'll do our best though try and make it look cool like I said it's going under my desk if it's not absolutely perfect I'll live with it alright actually I think that's all right how's my first one look little rough even not too awful bad alright let's move on the next one again I'm going to use the factory edge here for my starting point get my parchment up here and here we go [Music] sometimes you gotta go back and heat up a spot maybe didn't burnish down as well as you think it might have like on this edge right here seems to be usually right on the edges where it's like it's coming up again moving just hit it again [Music] pretty good this is what we found is you suppose you need to turn this really close where the little edge trimmer thing doesn't work well get it close as we can to start with and then we use this edge trimmer here [Music] you [Music] so just sanding the edges with a little fine sandpaper this is 320 grit and I'm just kind of cleaning it up a little bit like I said it's not terrible it's not great I mean if you look at it closely it's not really all that great but no it's it's better than it was and just say that see if I can get this opened up somehow one word about this stuff when you're when you're working with it to take it out of the package and cut it be real careful with it because it is super brittle I mean you look at the stuff it just just cracks really easily and the stuff that I bought actually was damaged there was probably twenty percent of it was unusable because somebody had punched it or hit it or something and cracked it through the box or maybe it was a return somebody got it and didn't like it and didn't put it away right but anyway it was damaged and was most a lot of it wasn't usable so I had more than enough to do what I needed to do was only like $25 so I got enough to do probably another one of these cabinets if I wanted to so I'm not gonna fuss over it but anyway where do the Y's just be careful with it no I think we're to the point now where we can put some electronics in this thing which is the part I've been waiting for so let me clean up a little bit come back we'll put some electronics in this thing okay so what we've got inside here and why there's so many there's only two speakers in here two subwoofers but there are eight wires here so what we have is two speakers that are both what's called dual voice coils so because each one has two coils what it does is it allows you to change the ohms and by lowering the ohms you can get more power for less ohms it's a lot of electrical theory and all that stuff not going to get into that look it up how to wire dual voice coils a lot of car audio people deal with that so I did some research I made some notes and we're gonna wire this up that way I will put a diagram up on the screen when when I get to post-production doing my editing so you can see exactly what what we're gonna do is we're gonna pair these up so we're pairing the negatives and the positives together [Music] okay so what I've got going on here is I have bound together on speaker number one which is the visible one I've bound together the two positives and the two negatives into a set of wires here with red and black for positive and negative and then on speaker number two which you can't see it's inside there I've bound together again the two negatives and the two positives again black and red so the gray and the black are negatives on the speaker number two and the red and the white are positives on speaker number two the the yellow and the orange are positive on speaker number one and the brown and the green our negatives I'm speaking over one so what we're going to do is we're going to put these two blacks together here and we're gonna bind this into a little connector just like that and we will crimp that and I'll do it yep that's good and then we'll do the road here I think it was in there nice and good crimp them right it feels good okay so now I think we're ready to put this thing together so this is already wired for a subwoofer so all I got to do in this case now is put the black to the black red to the red there we go so let's check our fit that's the top all right so let's put I put some music to it and see what happens alright so powers are them I got the volume here to sell outgoings down the subwoofer volume is down powers on we'll go ahead and start the music [Music] [Applause] [Music] [Music] it's putting out a lot of sound a lot of sound there's the woofer by itself [Music] rumbly [Music] [Applause] [Music] well I think it worked so yeah cool it's more than a twenty dollar welfare now it's more like a hundred dollar subwoofer but I think overall turned out pretty good so let me get this buttoned up and we'll take a couple of final shots of it and we'll call this job well done [Music] [Music] [Music] [Music] [Music] [Music] you
