Hey, does anyone have any schematics or anything of use for an individual (eps) amp? There was water in my trunk recently and caused a short, blowing out the rear speakers and center channel.

Replaced the speakers now and everything works but the center channel. I'm pretty experienced with soldering, but just don't know which chip controls the center channel.

There are no immediate signs of corrosion or arching inside the amp.

This is the only instance I have seen of somebody sucessfully
repairing a L7 amp on there own .
You could try following a similar process and back beep that channel
to the appropriate chip. Then try to identify it.

Never seen anybody put anything up but pinout of the in out pins on the L7 amp.

Thanks for the tip. I decided to tear down the amp again tonight, and found one of the medium size capacitors very loose. The negative lead on the capacitor is severed! There were also minor traces of corrosion on some of the smd capacitors. I'm going to order a new capacitor and clean up the traces.

I'm guessing that the medium size capacitors are for the mid-ranges as there are 7 of them, and 2 large ones for the mid-bass' under the seats.
