how big is your power wire..the bigger the better..check your ground wires..make sure the ground wire isn't longer then 18 inch ground it good...also check to see if any wires are touching..the other might be that the amp isn't strong enough to push the sub..


i'm running two 12 L7 and a kicker sx.1250 watts class D amp, one kicker kx.200 watts amp, one cap and two batterys..no problem..
