Doing an amp install in the ef fairmont. The remote feed for the amp, what colour is the wire on the stereo side of the loom? I have 2 plugs in the boot, one has a aqua colour wire and the other has an aqua, yellow and black. These are for the amp and changer right?
I also am going to use a 4ch amp to run the front tweeters and door speakers, how do I access the door speaker wires so I can run independant wires from the amp?

when you open the door there is a black plug against the door and car speaker wires are there or that of the door trim and you will see the speaker with the wires attached to it. As for the amp wires cant help you there
