He guys I am having trouble diagnosing this sound. I can't figure out exactly what is causing it...but I have checked the ground and the wires to my amp...I get it first thing in the morning...when I engage the clutch to back out of the drive way, then when I engage to go back to first...but after that it doesn't come every time I clutch???? It also seems to come when I rotate my steering more than one complete turn....I know this is hard to diagnose but I can't seem to figure out exactly what the deal is...I haven't taken my door apart yet..so that is my next step...I have Kappa components running off a ZR240...but they have been in for over a year and this has just started in the past week...any ideas on what woud give me feedback from the clutch and the steering? especially when the car is still warming up? thanks in advance....

 

double check your ground on the radio and the amp.

 

shouldn't the radio be chasis grounded from the surrounding frame? I did check all the connections on the amp itself...

 

you want the radio to have a common ground with the rest of the equipment(amps, etc). Make sure the radio is grounded to a common spot like a bolt to the floor or something. If there is a difference in ground potential, you will get noise.

 

well for once I actually didn't do the install...but though the HU always comes with a ground wire as long as it is bolted to the existing bracket you still get a ground with that...but like I said I didn't install the HU so he may have actually used a ground....I guess my confusion is the fact that it is an intermintent problem...
