i installed a full audio system in my car, subs, speakers, amps Head unit

when i listen to it with the car off it sounds perfect but when i turn it on there is static coming from the speakers and when i hit the brakes i hear a static pop in the speakers what the hell iis going on

 

Check your grounds, connections, etc. Are you using bobo cables, or quality cables? Do may have to bump up to wires with thicker insulation.

 

Are all of your wires (rca's, ground, remote, etc) running down the same path? Are they next to each other?

 

yes they are , but it only does this when the car is running
