The fader feeds the rear power amps on my 560SEL. amps are behind the rear seatsone left one right. Can't se how youwould fry an amp just cleaning the fader. the amps take a normal speaker signal of 8 ohms. I had to replace my becker witha blue dot miami a few weeks ago.

The amps are not low signal input. I had to feed left and right speaker signal right into the fader. The fader is about 500 ohms and allows the front and rear split, so the right amp is two amps: one for front and one for rear.

Point is two: 1 throught the fader you can feed it with lots of power, mine is 4x25watt out of the radio. 2 just get a used amp. Gotta be cheap, who wants them? ** to by pass fader and the amps, you'll have to run new wire to the output of the two amps and splice into the speaker wires there. Its a lot easier pulling the back seat and testing the amp. try jumpering the good side to the no sound side at the fader. maybe you just hurt the fader.
