Who needs chimes anyways But if your really wanna stay with the factory deck and run amps I can't stress enough that make sure you get a quality line converter. I have had SO much noise through PAC boxs and other similar items on my GP. Check out AudiControl LCi6 if your serious about it. Ebay has somedecent prices on them. Or you can go my route and scrap it all and run all new wires/speakers/radio ect... I'm not going to be.using one bit of factory installed audio equipment once the Eclipse deck is in.
