I have a GTP coup and I just pulled out my factory system and installed an aftermarket one. I run my rears off the new deck using the existing wiring. I think the existing wiring runs from the deck to the factory amp and then to my speakers. It's messing up my rears bigtime. I could run wire directly from the deck but i dont want to take the car apart again. If anyone knows where the factory amp is please let me know.
thanks.
thanks.
