DIY BOSE Subwoofer Repurpose / Rebuild

- We teardown and repurpose a BOSE Acoustimass 6 Series II subwoofer that we bought from Craig's List, turning it into a usable and powerful 2.1 front firing powered subwoofer capable of also powering two decent sized satellite speakers with premium sound.
BOSE Acoustimass Surround Sound Systems are popular, and are not cheap systems when they are new. There are many of these expensive systems out there that have been broken up or have been replaced with something more simple or less expensive, they are out there and you can find them cheap! The Acoustimas 6 has two very nice 8 ohm Dual Voice Coil DVC subwoofers inside that pump out a ton of bass and give you some flexibility of powering them as a 4 or 8 ohm system.
In this example we bought a BOSE sub woofer for $20! I went to my new favorite audiophile store, Parts Express and purchased a Dayton Audio MCA2250E Class D Plate Amplifier with 2.1 Surround capability for $65 and a pair of Dayton Audio B452 4-1/2" Bookshelf Speakers for $27 to make a cool DIY desktop system to use in my office.
Along with taking apart the BOSE Acoustimax 6 Series 2 subwoofer and replacing the electronics, I also had to remove the vinyl veneer that was coming apart and applied new iron on Band-it black melamine to refinish the outside of the particle board and replace the vinyl covering that was peeling off. Trimming melamine, as I find out is not as simple as it looks!
This DIY Project was pretty easy and anyone who can use a screwdriver, a hand saw and a pair of wire cutters can likely follow my lead and do this project. All in all it turned out pretty cool. It's a TON more than my home office can handle and the bass shakes the whole second floor of our home! The BOSE subwoofer has a new life, looks great and it worked out better than I expected. A cool rainy day project indeed!
Enjoy and I hope this helps!

The smile he gave when the bass kicked on. Pure joy!
Nice Job! I'm doing the same with an Acoustimass 10 picked up with the cube speakers for $75. Thanks for the great video how to!
Those drivers are 2ohm per coil, so your pulling a 0.5ohm load from that amp, lucky we didnt see the magic smoke come out, great mod as there is plenty of these old Acustimass modules kicking about and they are pretty good for boomy base, but by removing the internal crossover, you have removed the safety bulbs that are onboard to protect the drivers from blowing, I know as I have done a similar mod, you can overdrive the 5" drivers pretty easy and not know due to the bandpass enclosure.
I was using a voltmeter on three different series speaker from the acoustimass line. They are actually like most other home theatre speakers; 5.6-6.7 ohms rating. Not all Bose speakers are 2ohm.
True, they seem to use a large variety depending on the year, model and series, I have some 1ohm Bose Bass Drivers here as well, but these are usually found in the Automotive bass modules, and I have one that is ridiculous, 0.5ohm rated, I think that is from the Chev Volt, the newer AM10 with transmission line setup are 4ohm and most of the older AM5's are around 6 Ohm@@dannylewandowski2822
That was entertaining. Like a cool version of This Old Sub. And just when I thought a loud version of There's a Tear in my Beer or Knights in White Satin was inevitable.... you bring something to really test the sub to the table. Hats off to you sir... You've done a fine job.
Dude. For all the tools u got....do you have a router? It cuts that board so much better and cleaner.
Are the coils from one woofer 8 or 16 Ohms ?
If they are 8 Ohms after you connect the coils in parallel from one woofer you get 4 Ohms woofer. After you connect two woofers in parallel you get 2 Ohms and it's not "healthy" for the amp.
Nice mods, safety first, you must test the final impedance of the speaker before hooking up to amplifier.
Wow, this was your first video? I think it was great! Too bad the copyright scans got ya on the music. Check out the TH-cam Audio library and that will save you from those issues in the future.
ood job looks good hard to tell what kind pf bass comong out unless u are there ive built subs and speakers over the yrs as a hobby looks good keep it up thanks .
I have a AM 5 series 2 and want to do the same thing with an amp. I am currently using them as my rear surrounds but not with the Falcon Cubes. The are paired with Bose 100s. It's sounds so much better. Really enjoyed this D.Y.I.
Aren't 3 speakers in that box? I have a similar passive Bose subwoofer and it has 3 speakers inside, 2 double coil and 1 single coil. Great video by the way!
I just made one of these thanks to your video. I found the same Bose you used at the goodwill next to a pair of 60’s era KLH model 6’s. I have it hooked up to my ps5. Thank you for this video!
I loved this project, watched the video all the way through. Maybe you'll get around to uploading more in the future.
Thumbs up for the fridge in the workshop alone !
Well done!. For $102, plus the melamine, you now probably have the best powered desktop system around under $250 and other than the sub-driver, it's "new"!. Another option someone could consider for a similar project is to use exohyde or some other speaker cabinet paint, which would be quicker and easier than the melamine.
This makes me want to do something else with my desktop setup (Currently M-Audio AV-30 powered speakers - they are "ok" for this purpose, though completely blown away by your setup) but I'll be returning to the office in July, so not much point.
I picked up one of these a couple years ago at the local charity shop. It is in excellent working condition, such as it is. I bought a Fose mini amp with 100-watt, one-channel output for sub which I will run off a Fiio DAC from iMac digital out. Want to pair it with Monitor Audio Bronze One speakers for my desktop. Not quite sure how to wire it. I guess I'll jump the sub out to both inputs on the Bose and run the speakers from the two 50-watt stereo channels of the amp. I'm hoping for passable sound at best here.
Well-done, a great first video shame you haven't posted since. They are beasts and you can really crank them up. I picked up an Accoustimass 10 from fleabay.
I was literally just wondering if I could repurpose my acoustimass 6 sub unit, before pitching it.
Sir kindly please let me know the name of black paper or buying link. Thank you!!
The reason for two voice coils is to preserve the integrity of the stereo signal on the passthrough while still providing a signal to the subs.
Means?
I like the cut of your jib.
Subscribed.
Thanks for the great video . Have the same sub. Someone had wired it to 8ohms. It's very quiet. I will wire it to car amp. 4x2ohms Now i know the positive and negative wires on the woofer inside. Thank You.
I have a acoustimas series ll and it has 3 subs in it but problem is the foam surrounds are crumbling and no way of getting them out due to the sealed chambers. I bought them in 2003. Don’t know why they wouldn’t use rubber surround.
Because Bose is super cheap - but at the same time really expensive. Really, they're business model is to use the cheapest parts, assembled in the cheapest ways, and market the sh*t out of it to lure in as many untrained and ignorant "consumers" as they can. It's mainly worked really well because of the lack of knowledge of their customers of what good sound quality and performance actually sounds like.
+The Original Trailblazer I got one exact one gifted to me. I'll do a similar conversion. Thank you.
I reccently got a pair of massive polk audio rt2000i towers.. A little pealing, missing a couple feet, but for the price compared to how they sound, I dont think I could care any less about how they look lol. (side of the road specials)
Those are the best kinds of quality speakers - free. They'd blow away anything from Bose too.....
@@Ezees23 whats funny is a few weeks before that, I had bought a 7.1 channel set of polk speakers. The rear speakers in the set didn't work.. guess the fronts are now the rears, and the frees are the fronts! I think I know why the rears don't work, something in the crossovers.
@@danielauen7790 Wow. You've got some "Days of our speakers" thing going on over there, LOL....
Interesting.i saw one driver with two coils so I assume 8 ohm/8 ohm= 4 but the other driver? What impedance was that one??
Your first video? Nicely done. And not bad for your first foray with melamine. That stuff is always a pain to work with. As for the speakers, nicely done. 👍
Is that a car battery you have running something in the back at the end of the video?
Are you doing any more speaker projects? That was a great video.
How can I take the bose gs series ii speaks and rewire the speakers to a home Yamaha receiver?
I want only 2.0 amp to fit on it that drives the existing crossover.
25:34. I would recommend soldering in a sub, the vibrations will make the crimps eventually fail.
I have on old lg 5.1 surround system. It was cheap and for pc. I dont really have the space to do a proper surround system right now. I got presonus eris 3.5 bookshelf speakers that have bluetooth capability. If i were to harvest the sub from the lg system would i need an amplifier board with bluetooth or would the eris speakers bluetooth work. Im thinking they wont but i figured id ask just in case. I mean i know the eris speakers would play but im wondering of the sub would too.
Good job 👌
how cool. always wondered how to do that and what the inside of the bass module looked like. looks good to me....how's the class d amp sound?
I have the powered version but the ancient CD player/receiver doesn't work, wish I knew how to trick the speaker into turning on or which wires to splice for input.
You can order yourself a cable which will go from the sub to a regular 3.5mm headphone jack. Then you can use it with your phone
I have a acoustic mass PS 28 and another one that is bigger I would like to do that too but do you sell any
I want to do this with a Bose acoustimass 15 ll. But not as savy as you. Can you give me any advice?
Use a heat gun to peel that stuff off .
i would have liked to see how you got the speakers in there
Speakers are built into the cabinet, there is no way to get them out, or even access them, with out completely disassembling the cabinet.
Thanks for all your info and efforts!
Do you sell those I have a customer SPS28 but I would love to do that with and I have another customer service a little bigger
Is it any good?
Good dayton audio
all the speakers you connect in parallel means the load at 1ohm is not good for power amps and
You have a good point... How long the Amps will last
👏 great video! So I have an Acoustimass 10 series II that I want to do the same thing..I see that there’s 2 extra wires on mine. On one connector I have the same red/white/black/gray but on the other connector I have yellow/green/red/black/orange/brown. I am not sure what the red/black for the latter connector does. I am trying to find out on the web, but figured I’d ask if it was ok to just wire it like you did? Thanks again for the video.
Update, I got both speakers inside the sub up and running. I do not know what the extra red and black wires do but I have taped them off. Sounds amazing
@@ionicbreeze The Am10 ii has 3 woofers in it. You may have only 2 hooked up.
Would this work on Bose acoustimass 10 series II ?
Отлично замутил !
Hi do you have a old passive bose crossover not that expensive for 1000 Indian rupees if yes pls let me no
Sorry man, I do not sell parts or things like this, just playing around in my garage with some old used stuff! Glad you watched it and I hope you are inspired to repurpose an old sub like I did.
@@theoriginaltrailblazer1200 then if you could please give me a actual circuit diagram of bose and the components so I could do it on my own.for My personal use that's it My email ronald.fernandes72@gmail.com I will be ever great full to you.
powerfull 4x50watts rms ,the only problème is FOAM surround
Over talking, 🦬
Where can I buy Dayton amplifier ? from Philippines
It looks like the amp has been discontinued!
www.parts-express.com/dayton-audio-mca2250e-2x22w-50w-21-channel-class-d-plate-amplifier--300-771
I did just buy one of these - and it is pretty good for how small it is.
www.parts-express.com/dayton-audio-dta-21bt2-100w-21-class-d-bluetooth-amplifier-with-sub-frequency-adjustment--300-3831
So far my experiences with Parts Express (.com) has been exceptional!
Awesome
Exelent!!
Good job ;)
Why buy a amp if there was one you pulled out?? Why not figure out how to use what ya had for $20
There was no amp in this subwoofer. The device I took out is some kind of crossover that separates out the low pass signals and then sends the input power through the sub speakers and off to the satellite speakers. There was no electric power going into this sub, but there is now!
@@trailblazerb1 strange i picked the same amp up at a local goodwill for $12 and had the amp for the sub and additional 2 outputs that also run through the amp
You hv not yet responded that's very bad
My pioneer DJ sounds better than that
