I have the same problem.
A lightning strike has rendered my P1000 quiet.
Not ENTIRELY quiet though.... I can here the low-level signal come through. As if line level is making it all the way to the speaker.
But when I turn up the volume control on the remote control box, a 60Hz hum noise gets louder, but not the bass.
When I turn up the receiver feeding the P1000, the bass gets louder.
But where it should be rattling windows, it's but a whisper.
I looked at the BASH amps, and apparently it's a BASH amp on the P1000, I'd actually have ZERO issue replacing the remote control panel/BASH amp two-piece system with a new amp that has the controls right on it.... EXCEPT the P1000 puts the amp on the bottom of the sub. Not the most ideal place for something that gets hot, and there is limited space/depth to mount the amp.
I think I could "potentially" turn the sub on its side, making the bottom face rearward, and then I'd have to fashion up a new enclosure for the BASH amp, and feed it in to the two speakers, but I'd have to see how CSW wired them up (series / parallel) and does anyone have info on the resistance of the speakers CSW used?
I'd appreciate some advice on this concept.
