I just installed a 4 channel amp in my R last weekend, and it worked fine for a while. Now it gets real staticy when i turn it on, like i can kinda hear the music but it sounds like ****. I have two channels running my front two speakers, and the rear two bridged to a sub. any suggestions?

 

1. Check the amp ground.
2. Check the RCA's.
3. Check for any shorts along the speaker wires.

If problem continues bench test the amp and deck.

 

well it works sporatically, so i assume its a fault in the wiring somewhere, will check tomorrow during work. thanks
