I don't understand the 'cross wiring' aspect. If you wire in an aftermarket stereo and it plays, you could have a faulty radio producing no audio outputs to the amplifier. A faulty amplifier would also be suspect, but if changing a stereo causes audio, it confirms the amplifier is functional. The amplifier is powered by the cigar lighter fuse in the i/p fuse block, that is worth a check as well.
