Would it be possible to attach various speakers/subs.
On my SC-AK320 Shelf System I want more bass in my music. Would it be possible in any way to attach different speakers on to the system, or use the auxiliary outlet to connect a subwoofer so the music would simultaneously go through the original speakers and the sub?
I suggest that you can connect a subwoofer through a Pionner's like power amp and adjust it only with lowpass filter...
you need a battery and a charger. and that's it.

it is completley possible that your sub has in fact blown itself out mine has some CRAZY excursion to the point ive turned down the bass on my laptop in hopes to keep it alive so order a new sub SPEAKER if the speaker works the amps FINE
It may be a faulty relay, check speaker wiring for shorts, and try again, also if additional speakers were added remove them, that is a sure bet it is the problem. If no change! unit will need to be checked out by a professional.
I wouldn't expect huge bass from those little speakers. Somewhere on there, there's an equiliser, where you 'll probably be able to turn the bass up and down. See if that works. If not, new speakers may help.
Is it possible that the speakers are out of phase, where one speaker is moving out, the other is moving in, resulting in zero bass?
Other than checking wires, making sure + on amp is linked to + on speaker, try changing the eq settings, or sit them next to a wall - walls help bass a lot.
I cannot exactly solve this issue but I can make a comment based on investigation. Lots of people have this issue but there are very few comments to help solve the issue unfortunately.
I have the same issue and have been able eliminate various things because I have a second complete Bose Lifestyle 5 system.
It is clear the issue does not lie in the Sub and is related to the Music centre unit. I can use a second identical music centre to power my sub just fine and my broken Music centre cannot drive my second sub.
Now the issue is knowing where to track down R428 in the music centre which is the suggested fix to this issue. I have opened my unit and there are resistors various Resistors in the 400 range but no R428.
If anyone can help with the location of R428 in the Music Centre I would be very grateful.
Check the physical condition of subwoofer to make sure that the surround has not rotted out or been blown away. If ok, then using an ohm meter check for the nominal speaker voice coil resistance to make sure it is within spec. If both of these areas are good then you have destroyed the output stages of the amp(s) driving them. Every 3 db of bass boost doubles the output power. So if you are blasting along at 100 watts and you jack up bass by just 3 db the amp now has to put out 200 at those lower frequencies; go up by just 6 db and you are now talking 400 watts! And what does that do to an amp when you over drive it? You guessed it!
