I give. Is the next step to bypass the amp? Seems like this issue is pretty common with no one saying they have found a solution.

 

I just dealt with this myself. I tried everything and still got interference so I ended up bypassing the amp. Should have done that to begin with.

 

I had same issue even after new ground ran from head unit. I ended up putting in a ground loop idolater and it worked for me. I did lose a little volume from this but until my house is done and have a garage/tools to use, this was my quick solution that has paid off

Monoprice 106909 Four Channel Ground Loop Isolator - about $15 on amazon

 

I will check that out. I was hoping for a quick fix. I don't have time to do a full audio install before my drive across the country in a few days.

 

Do you think this will solve my problem if i get noise out of the speakers even if i have the rca's disconnected. I guess for 15$ it wouldn't hurt to try

 

It didn't work for me, but might as well give it a shot. I had noise with RCAs disconnected as well. Definitely an amp issue.

 

In my situation unplugging the RCAs from the headunit did get rid of the noise so does sound like you have another issue.

 

Just a heads up. Ground loop isolators helped but didn't do the job. It has to be a problem with these amps. Either way I pulled it out and replaced it with a jbl ms-8. Problem solved. Now I have a 49 hour drive ahead of me to tune it. Thanks for all the help and suggestions.
