Ahh it makes sense now to me -
From HU (with 9 wires)
Blue - Remote turn on lead
White = LF +
White with Black strip = LF -
Grey = RF +
Grey with black strip = RF -
Green = LR +
Green with black strip = LR -
Purple = RR +
Purple with black strip = RR -
So I ignore the rear (tape these up) as I am only using a 4 channel amp to amp front speakers and under seat subs.
So I get a RCA connector and fit on LF + & -
Then another RCa connector RF + & -
I could do the same with the rears and RCA - is there any benefit of having this connected?
Then on the return loom, same configuration as before but I fit
channel 1 - LF + & -
channel 2 - RF + & -
Channel 3 - L Sub + & - (the black cables with connectors)
Channel 4 - R Sub + & - (the black cables with connectors)
i think that is right? Can someone post a link to the correct type of RCA's needed?
