There is a light green wire on pin 1, connector 2 for the radio. That is the trigger wire for the radio/choke relay. That is what sends power to the amps. If you hook that wire to the power antenna output on the head unit, it *should* power the amps, and your speakers *should* start working. Crutchfield offers adapter harnesses for most applications, works MUCH better than cutting/splicing wires in the dash.
