With me, i have 2 audiobahn 12's, and an audiobahn amp with an intake on the top of it. I took out my passenger seat and mounted it underneath there. I put the amp on its max watts, and it will stay on all day if i throw the floor a/c on every 30-40 mins. The amp is hella small so it only pushes about half the watts of my 12's, so i think imma buy another audiobahn amp...
