I have 2 cvrs in a middle slotted ported box. So i turn up the volume everything good until i close my trunk it starts cutting out...so i open the trunk again and the subs pounding good....so i check my ground, power, gain etc...and everything good..i close the trunk and they start cutting out again..so i pop the trunk open and i put a 2x4 over the ported slot to cover it and the started cutting...is it the box or the subs??? any suggestions??
