I've recently installed my system and thought everything was fine. Until I started it up. I get semi-crackly high pitched interference at idle that turns into a high pitched whine that changes w/the revs of the engine.
I've seen a thread on this before but I searched and searched and couldn't find jack. It may be important to note that the interference sound coming from the speakers stays on even if the head unit is powered off, so it's definately something to do w/the amps.
Would a ground wire kit for the engine fix this? Be a good excuse to get one. Do I need to move my power wire around in the engine bay and find a better spot? Do I need an additional ground somewhere else?
This is a pic of my ground block. One ground for each of the amps hits that block where the wire turns all thick and that's bolted to the front left bolt that has the cargo hook on it under the carpet there in the trunk. Is that a shitty ground spot or what? Help, this shit is driving me insane!
