Yet Another Stereo Question

So we managed to get the deck out, and got the wiring harness' all setup, then we found out there's some sort of a factory amp that wont let sound past it without having a factory ford stereo in there, is there any ideas on how to get rid of that bugger without re-wiring the speakers because the last owner went on a little bit of a...super glue craze with the speaker covers, The only idea I can think of is cutting the wires and soldering them together and then tapin em up, but I have not a clue which wires, so if anyone would be able to tell me a coloring code for a 90 lx mustangs factory amp, that'd be great.
