ok when i turn on my cay there is a buzzing sound coming out of my speakers. i ask around and someone told me that its my power wire from my amp messing with my rca wire and that i need to run my rca wire on the other side. so i did but i still hear buzzing. anyone els know why?

 

It could be ground noise. Make sure you have a good ground, and it is not the same place as a factory ground. If you know how to do a voltage drop test, now would be a good time to do it.

How do you have the wire grounded?
