I did some research and talked to a few stereo shops and they all said that a power line noise filter is only for when the noise increases/decreases with engine speed or if the noise is consistent with all music. The noise I am hearing does not depend on the engine speed and is not consistent...

I have both RCA cables, remote wire, and HU ground wire running on the opposite end of the power cable. I have also tried a different set of RCA's with no success. I found this chart: http://www.crutchfieldadvisor.com/ISEO-rgbtcspd/learningcenter/car/noise_diagnose.html and following along...

When I disconnect the RCA cable from either amp, then yes, the noise does go away. Once I plug the RCA's into both amps the noice comes back. If by pass through RCA cable you mean having the RCA cable run from one amp's output to the other amp's input, then no. I have a RCA cable connected to...

Okay, I just finished swapping to a different HU that I pulled out of my other car and guess what, the noise is still there so the problem is not with the HU. I've checked almost everything else and I'm at a loss. I've elimintated the RCA's, amps, grounds, and now the HU as the problem. What...

Wish I could, but I don't have any spare HU's lying around. Do you think it would be a good idea to try to ground my RCA cables? Don't know if it would help, but it might be worth a shot since others have solved some noise issues by doing that. I have a bunch of spare remote wire lying around...

The HU is a Clarion DXZ845MC. I also did another test where I ran one amp at a time and the noise was gone. Once I reconnect both amps and start the car, the noise comes back.

I never unplugged the RCA's while the power was on. If what you are saying is true, wouldn't the noise be there regardless of whether or not the engine was running?

I checked all my grounds and all of them are fine. I just ran a new ground for my HU to the same spot as my amps. I now have a HU and 2 amps grounded at the same location. I also swapped out one of the RCA cables for a spare set I had. New HU ground and a new set of RCA's and there is still...

any thoughts?

I've been doing alot of searching on several audio forums to try to find an answer, but finally I am at the point where I have to post my own question. Recently I am hearing plenty of noise coming from the HU. I installed the system about one year ago and never had a noise problem until a few...
