I want to bypass the factory amps in my 98 Navigator and use the power from my Kenwood MP922 but I can't figure out the easiest way to do it. I don't want to try running new speaker wire through the truck...

Can anyone tell me where the factory amps are located so I can just splice the factory wires? I know there's a sub amp in the back by the 8 inch sub but I can't figure out where the other speaker wires are....

Thanks,
Chris
