teabag Posted December 9, 2008 Share Posted December 9, 2008 There are three circuits to the rear sub. 12+v amp power taken from the head unit supply, (light green/orange wire at the amp, also a local earth wire which is black at the amp). The 12+v amp switching wire (purple/yellow at the amp). The audio signal cable (black & white wires in a screened cable). So all you have to do is locate the wiring at the dash and extend and connect to your new head unit at the relevent terminals. The colour code may be different in your year of disco.
