I was wondering if the bose speakers in the 03 coupe have the 2 leads going from the amp to each speaker or are they wired a different way. Reason I am asking is because I was planning on upgrading the speakers and I was wondering if i have to run new wires. Thank you.

 

You can use your bose wires. I'm doing my system right now and that's what I'm doing. It's a lot easier to use the factory wiring because of the way it goes through the door.

I'm replacing amp, speakers, and head unit and this is the easiest way to do it. If you're just replacing speakers it's even easier because you don't have to splice into the wires where the bose amp would be.

If you are replacing the amp the colors at the bose amp connection are grey and yellow for right side front and red and green for left side front. They are on the blue harness and they are twisted together.
