[QUOTE="danny_isr, post: 597157, member: 556475"] I already did a search on this forum , and I know about the common answer grounding grounding ... So I went and did that, but no success The full story : I have a Premier 860 running two brand new kenwoods amps(8401 and 6401) in the trunk . Honda Civic Sedan LX 92 3 pairs of RCA’s and speakers wire on the right side of the car, power on the left. I disconnected the RCA’s from the Amps and the noise disappeared. so my conclusion – it’s not the amps . The amps have each one monster 8 gauge cable to the car chassis (both in the same point). So I went and connected the black minus wire of the 860 to a different point – one of the car bolts. And wired another 8 gauge wire from the deck body to the chassis (different point of the black 860 wire) – very solid. Same thing, still got that whining. I actually can hear it even before I start the engine. I can hear I guess the ECU or something like that When I turn the key on. What should be the next step ? how can I determine if the noise is from the RCA’s or from the Deck itself ? Another issue that I had during this install and I don’t know if it’s related or effecting anything here: While I was pushing the deck back to it place. Suddenly everything died. I checked the 12V wire that feeding the deck. And it showed only 1v. When the engine run I got 3.6v. Didn’t find any burned fuse. The clock of the car seems to be effected as well. And the LCD is very weak . So I took another 8 gauge wire directly form the battery to the deck AND connected it to the old 12v wire (the one that shows only 1v) and then the clock came alive. I did try to run the deck disconnected from that old 12v wire but it didn’t effect the whining . Will appreciate any suggestions Thanks Danny [IMG]//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif[/IMG] [/QUOTE]
