Stephen Posted September 22, 2008 Report Share Posted September 22, 2008 You could turn the amp crossover to HPF and set it at about 70-90 hz. Or you could use the headunit settings if you got them. or last option cheap bass blockers from crutchfield.com you can cook bacon shirtless if you're not a pussy...lol not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.
