Wires for amp signal on non-mach stereo?

[triggz]

Does anyone have a diagram or chart for which wires are the +/- speaker inputs for the rear speakers in the main wire loom in the back? We are adding a ~1000w amp/sub, already have a hi/lo impedence converter with rca outs so all we need is to find what wires to tap off of.

TIA

I searched around in the sound forum to find the answer you were looking for.. if you wanna trust my memory, i think the RR speaker white/blue is + and the LR speaker orange/green is the +

Cheers!
