https://www.the12volt.com/installbay/forum_topics.asp~FID~22 Read the grounding topics. Also make sure you have set your gain properly. ------------- Support the12volt.com

Turn the gains of the amp all of the way down, does that get rid of the noise?

With the gains all of the way down, can you still reach your desired listening level? If so you are done. If not turn them up until you hear the noise and back it off just a touch. Then see if you can reach your desired listening level.

Is it a pioneer radio? If so i have seen numerous of them start whinning for no apparent reason. They say the rca is fused and it will pop if the amp looses ground and trys to ground through the rcas. I never found a way to fix it usually have to replace the radio or if it is warranted try returning to pioneer.

The Pioneer issue is not your problem. You said it is barely noticeable. There is a way to permanently get rid of it. That is what the gain adjustment is for.

This is the first I remember hearing about the noise being in only one channel. Is this really your case? Or is it just more noticeable in one channel?

I know on my Pioneer AVH-P5700DVD I was getting a whine in my system. I went over my grounds, changed power sources, swapped RCAs and did everything else I could think off. After posting about it someone here suggested a site that basically said to take the jumper wire and ground it to the HU chassis and to the outer shield of the RCA (with the RCA still connected to the HU) and when I did this on mine the whine went away. I had to get out my soilder gun and soilder the jumper wire on the outer shield of the RCA and then crimped a small ring terminal on the other end and grounded it to the HU chassis. My system is crystal clear now. I dont remember the link right now but do a search for alternator whine and I am sure you will fine it.

If it is just a ground loop a PAC ground loop isolator should fix it. It fixed mine and it as simple as just pluging up your RCA's to the PAC. The post above should fix it as well with lower cost but more work. -------------
