[QUOTE="daBOODA, post: 3631, member: 541158"] I was hoping someone could give me a hint or two about what is happening with my stereo. Here's a little background information first: I have a Kenwood Head unit with two rca outs. It leads to a lanzar vibe 4 channel amp. Two channels on the amp are bridged to a JL 12" sub-woofer and the remaining two channels are powering a set of Kenwood 6" 2 ways in the front. The power wire and rem switch wire are both run down the left side of the car, while the rca and front speaker wires run down the right side of the car. The power wire (8 gauge) is connected to a fuse in the engine bay before it goes to the battery. The system worked brilliantly until I decided that the earth 4 gauge wire (which is earthed on the bottom of the boot (trunk)) was too short so I got a slightly longer wire that was 8 gauge and connected it up in it's place. As soon as I did that, a dreaded popping sound came from the speakers whenever a track changed on the CD. Also, when I started the car, I noticed that there was heaps of engine noise! So I change the earth wire back to the original earth wire that it used to work on and the problem still occured. I've tried connecting two earth wires, that didn't help ... Anyone got any suggestions? [/QUOTE]
