Im getting a lot of noise from my stereo(interference) follows the throttle too sounds like turbo. I got 3 units double stacked a stereo eq and dsp, I soldered the ground from the eq and dsp inline with the ground from the stereo. Sometimes when the noise is occuring a hit the side of the stereo dash and the noise goes away. Wheres it coming from, and what to do to eliminate it?

 

Run a new ground wire to your battery up to your head unit and connect the head and EQ to that.

 

OK ill do that!!!

 

do you have any amps in the car?

 

yeah but the noise came when i added the dsp and eq
