thanks for the help kev415. should i pull out my stock amp? the guy at the shop told me to just tap into one of the wires in order to connect my new amp, but i'm not sure which one. he told me that i did not need to run new wires from the HU to the amp but instead tap into the stock amp? also i was planning on using the exisiting factory wiring to hook up a set of mb quart comps in the from and rear. is this possible?
You can pull the stock amp, but you dont have to. You MUST disconnect it tho. You could get the audio signal for the other amp as long as your new amp has High-Pass inputs. Even then, I would recomend running RCA's just because of the sound quality that is lost re-amping a signal. and running through little tiny wires the whole length of the car.
As far as the wire that you can pull off of your stock amp, it has to be the remote. I think it is a white wire off of the amp, but i am not sure, if I get a second, Ill go out and look at what I did on my car.
You can use the factory wiring, that is fine. I have some wiring diagrams that I will post tonight if I can find them of what wire goes to where. I got them off of the old board when I did it, so I dont know if they are still burried in there or not. But as long as you have the right wires going to the right places, those speakers shouldnt present a problem. If they are a component set, leave the Cross Over in the trunk and then utilize another set of the stock wiring. If the are full range, then just go for it.
