Re: Powered subwoofers

Thanks for the advice. I don't think I will be able to get a hold of the schematics as the subs are fairly old. They are a BIC V80 and an Aiwa TS-w35U. I will write the companies and see what they say. Anyway backtracking from the speaker wires shouldn't be too bad. There is plenty of room on the boards and not much surface mount stuff.

*edit* Oops, spoke too soon. Found the Aiwa schematic under the model number tsw37 here;

I have a collected couple of powered subwoofers in the garage over the years. Just couldn't make myself throw them away and always planned to fix them. I started that this past weekend and noticed both have the same problem or seem to.

They both power on, red light when plugged in and green light when turned on. I suspect the input is working because the auto on trips the green light when a signal is fed from the receiver and I hear the relay click on. I know the receiver's sub line out is good. No fuses are blowing and nothing get's excessively hot, just warm. I get no sound from...
