[QUOTE="eskimochaos, post: 4563152, member: 592287"] Well guys I had my system installed yesterday, My grandfather said that he would pay for it so I went for it. Anyway it sounds awesome but there is one thing. When there is nothing playing...volume at 0, there is a little bit of static/hum. You can only hear it when volume is at 0, it does not increase as volume does and it is not alt whine because it does not change frequency when engine is revved. It appears that it is my HU that is causing it. After turning off the car, the amps immediately go off but the HU remains on for an additional second...and the humming/static is still audible. Any ideas, I doubt that the installer created a new ground....he just used a wiring harness...should I have him look at it? You can only hear it at idle but for a total of nearly 2.5k it shouldnt be there imo. Thanks oh yea my HU is a kenwood DDX712 [/QUOTE]
