I have a 97 Ford Escort with pioneer speakers in the back with a 250 watt amp connected to them also 2 10" subs with 1200 watts on them and only when the car is on a buzzing/humming sound comes out and it increases as the rps go up all the ground points are on one spot and i also have a ground loop isolator connected to them so what could be causing the noise?
