New system...high pitched buzz/ring

Just installed and new system in my 2012 jk. I put a new deck,sub,amp(sub), new front and year speakers with front tweeders,amp(audio). When the deck is on there is a high pitched buzz/ring that goes up in pitch as I rev the engine. I have no idea what could be the problem. If anyone can help me out I would greatly appreciate it thanks

its caused by interference between the power wire and the rca's and speaker wires. you need to run the power away from the other wires.

I had the same problem and had every thing ran seperate and carefully. And found I just didn't need the speakers tab to an amp. Just the sub.!!! The jeep is small enough inside that the deck has enough juice to pump good sound to the speakers!!

Soo basically to fix this problem I either get rid of the amp or rewire everything soo that the speaker cables are on one side and the RCA is on the other right?

Run your power wire and remote wire on one side of the jeep. And then run your rcas on the other side of the jeep :-). That will fix it.... Please don't use cheap rca wires. They are diffently worth spending a few extra bucks for a nice set.

Also, check the ground wires for your head unit, and amps. Instead of using the factory ground that's in the wiring harness, tie that directly to an unpainted metal surface. Also, make sure that your amp has a good shiny metal ground. One last thing, you might want to turn the gains down on the amps, they are for impedance matching, not for "extra" volume. Oh, and what everybody else said about seperating the power from the audio, very important.
