[QUOTE="GTO Dave, post: 7189866, member: 593829"] Here's the deal - 2003 Explorer - just replaced the subs that my step son blew up(cheapo free ones that I had too much power going to them...I knew it was a matter of time). Built a new box for them and upgraded the amp. Now I'm getting a really high pitched hum when running and all the voices sound really tinny....all the dj's on the radio sound like they're in an echo chamber. The whine does not fluctuate when I rev the engine....it doesn't sound anything like any ground fault/loop issues I've experienced in the past. Also it only seems to be coming from the door speakers. Any advice? Maybe it is a bad ground on the amp? JVC deck - Cadence 4 channel (75x4@4 IIRC) - Polk coaxs(cant recall 5x7 or 6x8) - Alpine PDX 1000.1 powering 2 TB 8" subs. Also when I am playing thru my Zune the voices(treble?) sounds the same and you can hear all the clicks from the Zune thru the speakers.....doesn't do that it my truck..... Help Please!!!
