Non dsp amp wiring
 

I am replacing all my speakers and amp. I can not find any info (including in the Bentley) for which speaker wires control which speakers at the amp. I can find the colors at the speakers themselves, but none of those colors match up when look at the connection to the bmw amp. For example.. The left rear woofer is yellow and brown at the woofer... But there are no yellow wires at the amp. I tried rewiring all the speakers with new wires but quickly found out that the rubber grommets going through the doors won't accept any new wire... Bummer.. Soo..can anyone help me
