    Hello all,

    I'm writing on behalf of a friend who bought a JBL PSW-D112 a couple of years ago. The subwoofer has since stopped working. When turned on, it will function well for about 1/2 hour, then start buzzing almost like a bad ground.

    The sub is long out of warranty, and he doesn't have a lot of cash, so he'd like to just replace the plate amp.

    Any recommendations on plate amps that'll fit the bill?

    Your suggestions are appreciated,

    Chris

    I am currently using an old (discontinued) 120W amp from PE that works fine for my uses.. BTW, I have a very similar problem with the exact same sub. PE has replaced the model amp I have with something newer. I think it is pretty cheap too. Just make a box for it and rerun the speaker leads for the subwoofer to posts outside the box.

    make sure you cover the big hole in the sub where the plate amp was and seal it with silicone caulk so it's airtight. It needs to be airtight or your sub will be hosed.

    Actually, what I did was to reroute the lines inside my sub so that I left the existing amp mounted to the box and use one of the pairs of speaker-level inputs as inputs coming from the external amp. Elinates the hassle of fabricating and sealing anything else up.
