I have a couple of after market amps, and would consider installing those instead of the factory amp, but a couple of questions first:

1) I assume the DSP function is built INTO the factory amp, and is not a separate unit, correct?
2) If that's the case, wouldn't removing the amp make wiring the after market amps a bit easier?
3) Someone on this board must have had the wiring figured out by now. I haven't searched the forum yet.

Thanks - Samer
