Contour Enthusiasts Group Archives Forums Modifications Audio EXPERTS.....need help!!!....engine noise

Hey guys, i still have not gotten rid of that engine noise from my front components. I made a noise sniffer to figure out if it was the amp or headunit/rca's, and the sniffer said headunit rca/s. I replaced my cheapo rca cables today with 2 meter Dream Series Stinger RCA cables. NOise is still there. I also grounded my headunit to that little metal piece to the right of the headunit(underneathe the dash). I am running a kenwood excelon headunit. What the heck should I do???? I've done just about Everything I can now, any suggestions??--it has to be coming in through the headunit somehow/where???????

try a buddies spare HU It is a possibility that you HU has gone south. hook up a home cd player or portable with rca's and listen for the noise. did this one and it worked for me ( teh home unit hookup that is) Also, what about one of the other wires from the HU, other rca's, regular speaker wires , cell phone mute ect touching ground? how about the connection of the rca's to your HU. I have mine taped up to wliminate the possibility of contact with ground. I'd try this forst now that you know the noise is upstream of you amplifiers.

yeah i have to mess around with some of that stuff, if it is my headunit, do you guys know would it would take to fix it?? I'm assuming something would just need to be re soldered or connected....??

I had the same problem. I think it was my AMP ground which gave me the "whine" I have the Kenwood Excelon z828.........either ground your headunit to the same ground as your amps, or run the cables on another side of the car..

Hmmmmmmmm.........

See this thread.

Right now I think it is my headunit. Is there any way to test this the headunit to see if it is bad? There is a place around here that does that inkd of stuff.....what will it take to fix it?
