Have you always had the noise problem or did you do something recently that caused the problem?

 

[mikeyboy]

always got the truck with it

I would say start checking your grounds. Do you have an aftermarket amplifier in the truck

 

[mikeyboy]

i have a eq going to 3 aftermarket amps

I'd lean towards a bad ground somewhere, do you have your power wires running with the signal wires?

Sounds to me like a ground loop. With that much equipment, it could easily happen. It could be anything from a broken ground shield on rca wires or the components not making a solid ground.

hmm the power wires are on the opp side as rcas

Well, that's a good start!! I'd say check all your grounds and make sure they are intact and good!

agree, sounds like ground, or RCA's, you can start pulling one at a time to see if the noise goes away while system is playing.

I had the same thing. Even with a better ground it didn't go away, so I re ran my RCAs on the other side of the truck, away from the power. Problem solved.

i thought he had already stated that the power was run down one side of the truck and the rca's down the other

many others can read this post, other than the OP. Huck added some good info in case anyone esle watching has the same issues.

Agreed with others on here, Check your RCA shields, and with the eq there could be a ground loop my audio shop here in texas sells something for it, all you do i plug in your rcas ground the eleminator and run its rcas. If you get alternator feedback when you rev the engine then this is more than likely the problem but not alway. Hope this helps.
