[QUOTE="bds0688, post: 4446353, member: 574556"] My system consists of what's in the signature. For those of you without sigs. Phoenix Gold ZX350, Diamond Audio D661 and an Alpine CDA-9807 for the source. The Alpine is wired only using the power, ground, and ignition power, plus the remote turn on for the amps.
