ok here is my story, I have this wonderful set up(see sig) with no difference than when I had my L5's except my two new Fi SSD and a costume box. So I got everything in and it played at low volume which I might think is the box, so it doesn't get loud like I want it, so I figured I go with an aeroport box. So today I decided to switch my battery to the other side of the trunk, did that and now it still plays low but cuts out when I try to turn it up. My amp is still on while this happens but no bump. Know I figures it may be my ground on my battery, how could that be if I sanded it and everything. Do you think I would give the amp it's own ground instead of it going to the negative of my battery, because I neve heard of a sub not playing because of the box. So
me one help me.
