BOSE 321 Subwoofer Repair

[@PC-Addicts]

@LTNY928 Awesome - glad you found this video! It seemed to have helped quite a bit of other people with similar issues. I would say any solder you can buy at your typical hardware store should work to be honest. Also, yes, a first timer could do this as well. If you search my videos, I have another video posted on how to solder wires... you can basically use the same technique as that, coupled with this one. IF you have any questions, don't hesitate to ask.

thank you thank you thank you!!!! i had the same problem with my 321 system and repaired it myself because of this video which saved me a ton of cash. thanks again!!

[@robertinglis7063]

Same problem. Broken solder joints. resoldered all pins on both connectors. Easy fix! Working great again! Thanks for the video!

[@PC-Addicts]

@LTNY928 No problem, glad the videos/info is able to help someone else out. I asked my Dad for his advice regarding the solder question specifically: Rosin core would work fine. It's sort of against the law to use lead solder anymore (not big deal as long as it's not used on water systems). Also don't breathe in the fumes from the lead solder.

[@williamlynch2195]

I have the same system and love it. Turns out the same fault happened to mine. Thanks for the instruction on the fix, saved me boucoup $$$. I owe you a beer.

[@mariomelara]

VERY MUCH APPRECIATED!! I HAVE THE SAME PROBLEM IN MY BOSE321, AND WORKS LIKE A CHARM!! THANKS AGAIN

[@coosmac]

Thank you! Thank you! Had exact same problem, bit of arc and smoke from Sub-woofer . Was about to toss the whole thing then saw your video. Did exactly what you did and now works just fine......Thank you again !!!!!! :)

[@norman614808]

Thanks for the video. I have the same module but my problem is that I am hearing a loud hum and no bass coming out of the module. Any thoughts what could be wrong and a suggestion to fix it? Any response is appreciated.

[@deelolo875]

HI THANK YOU FOR YOUR VIDEO IT WAS A GREAT HELP . IT'S WORKING HOWEVER NOW I HAVE NO SOUND FROM THE SUB WOO FER CAN YOU HELP PLEASE ME. THANKS

[@verdielg]

Hi, currently having an issue with my Bose 321 not producing any sound and was wondering if you got your unit up and working successfully?

[@19rudy65]

Great info, thanks. How do you remove the plastic cover without breaking it ?

[@PC-Addicts]

You are welcome... glad it worked out for ya!!

[@thenguyen1]

I don't have the 321 Sub-woofer but the 2002 Bose sub-woofer Series III that recently broke down. It started to smoke and make a load humming noise. Is it the same problem that you went through, and can I fix it what it shown in the video?

[@baconlatte]

Thanks a million. Was able to revive my 321. However, my solder joints look like big blobs that are not well connected to the board.

[@shag2dabluzz]

Hi Chris,,,,recently purchased a working Bose PS-321 subwoofer only... identical to the one you're showing here. But, I purchased it in hopes that I might be able to use it in conjunction with my current laptop audio set-up. My question is >> which wires should I solder to a 1/4'' female plug-in to be useable with connecting it to my existing spkr set-up. too many to chose from on interior of spkr cabinet. PLEASE HELP!!! Thanks!!

[@PC-Addicts]

The soldering gun worked fine... the solder job is still good (use this Bose every day), and if it helps people get their system back up - then my job is done. Could it be better, of course... just about any online tutorial you come across could be better in some way or another.

[@gonzalle]

I found one of those 123 into a garbabe ! it is complete, even the remote and wires ! . but it doesn't switch on... i will try this and keep you informed !

[@kielbasaglen6843]

Would you happen to possibly know why the bass module from my 321 system would all of a sudden stop working but I still get sound out of the speakers?

[@PC-Addicts]

I do not, sorry :( I just recently gave this unit to my brother-n-law (still works great!)

[@rwillis11]

hey thanks for the video. i recently plugged mine into an outlet with too much power and it blew my fuse. i replaced it and there is power to the control unit but there is no sound until i unplug the system and it blurts out sound for a split second then powers off. any suggestions??

[@vanillasparklegirl]

Thank you for posting this video! I'm having the same problem with my sub( it sparks and smokes when plugged in) and I thought we might have to get rid of it. I'm going to try this and see if it works. Plus it was a good excuse to buy a new soldering iron. :)

[@LTNY928]

Just happened to my 321 subwoofer, only thing that needs to be soldered is where the power comes in (exactly the same location as in your video). What kind of solder should i use? and can this be accomplished by a first time solderer? lol

[@lawnside82]

what kinda solder iron u use? damn that thing is nice!!

[@MrIrrelevant2010]

I'm not getting any power to my 321 Media Center, I saw where someone said to replace the fuse in the sub. Where is the fuse located?

[@gersoncampos2783]

hi .. i lost the db15 cable that came with the home theater.. is there a pinout so i can build the cable? is it straight thru? thanks in advance.. best regards from mexico

[@janithmy]

Thanks for the video. I purchased a working Bose PS-321 sub-woofer and i try to couple my 5.1 Logitech sound system into it to get more bass sound. but sub-woofer don't make any sound. however when i touch the circuit board it makes hum sound. plz help me Chris...

[@mikebell4044]

Chris, I pulled out my old PS321 Bose system and plugged everything in and it powered up fine, but there is no sound coming from the speakers. I checked all of the wired connections and they seem tight. I did notice on the sub the serial connection had a little rust on it. Any suggestions to the problem? Thanks, Mike

[@andrewsiemonsma6298]

Do you know how to hook that bose subwoofer up to a regular sub pre-out?

[@fruitmix4health]

Nice video, I have one like this , my transformer went dead. I would like to know the voltage across the brown wires from the transformer so I could find a replacement. Please help me out cause I cant afford a new one.

[@waynestone9154]

PCAddictsLive, Please, my Bose Acoustimass Powered Speaker System sounds great for about 2 minutes (subwoofer & 2 cube speakers), but gets distorted later on. Can you tell me what is supposed to be wrong with it? Thanks.

[@mcozpda3392]

My acoustimass 800 sounded good and trailed off ... check cables and radiocd player ..and everything is fine but no audio .. turns .... will have a relay or fuse in ..and appreciate your help ... cheers ..

[@LTNY928]

@PCAddictsLive Funny you mentioned the wire soldering video, watched that one too haha. Thanks for the advice, much appreciated, definitely helpful! Last question, what type of solder should I use? i have some rosin core solder, and an alloy 40 tin 50 lead solder.

[@cazandrainbow]

Hi, My receiver (DVD player) is damaged and not functional anymore. Is there anyway i can use BOSE 321 speakers with my PC?

[@130rabarth]

Ho, i would like to know the electrical characteristics off the power supply?

[@jjsanchez2290]

You're a lifesaver

[@PC-Addicts]

jj limo Glad to help :)

[@RemoteExplode]

My Fricken Hero! :) Thanks buddy! -not to burden you with Quality control: but the receiver hub for the Freestyle unit ( same as cinemate. etc..: The Left Analog rcs input 'cold-soldered itself right off the wee circuit board. -!!- Tried to re-solder and still won't work. grrr... I'm guessing "Remove/clean/replace" ..rinse, repeat,,, -Hope for success. Otherwise, can you assist in creating a bose-flavored neutron bomb? I would appreciate. :) Thanks! lol

[@jovelwalter]

Hi, I have a Bose 20 system, one woofer and 5 cube speakers.... my system worked great but then I put it away for 2 years and now the console works great, the subwoofer works great but only one cube speaker... I hear the other muffle but very little... is not the speakers because when I move them around each works... seems like only one of the 5 channels is working... how can I fix this? please help.

[@PC-Addicts]

Might be what you see here in this video.... have you looked for cold solder joints yet?

[@omfgg3tlost]

[@nitstalkr]

Hi guys I have bose lifestyle 535 series ll, today when I turn on console it's making repetitive noise on my accoustimass and 5 connected speakers even I didn't play anything or I muted the console. I tried to plug in plug out, even reset the consol, power on and off but result is still the same. On accoustimass module green light beeps constantly and when I try to reset the console it takes me to a window on tv said plug in accoustimass cable to console or check ac connection. Plz any suggestions will be appreciated. Thanks
