i have read several post about running wires from deck to rear to splice in to bypass the factory amp. is there a way to do it without running the wires to the rear of the vehicle. i had a nissan with a factory amp and was able to splice the in / out to bypass it. is there a way to do the same with my 96 conti? if not is there a way to keep amp and tie it into my replacement JVC stereo? might help with sound since im gonna replace the speakers with Sony 200 watt 6.5's and 6x9's.
