I have a 2003 Focus and am not sure exactly how to hook up the amp without a power antenna wire. Any suggestions? Also, with two ground wires for the stereo, which one should I use for the line out converter?

Thanks,  Brandon

Usually you don't need a ground wire for line out converters unless the vehicle has a common ground system in it.

As for the amp's turn-on wire, just use the same +12 volt switched wire that is for the stereo.  The wire you want to look for will show approx. 12 volts with the key in "ACC" or "ON", but no voltage when the key is in the "OFF" position.
