this is my setup up I finished this stage last summer. I wanted to have the spare so I made a fiberglass box that wraped around the tire. But I just finnished the first box and It sounds ok but not like I want it to. Especially all the work and time I put into making that box. So now what Im asking you guys is what should I do? take the spare out and make a square box to go behind it? Or should I get free air bass speakers?( I dont know how these work). Or any other Ideas? If your wondering I like my bass to sound good and flow with the music. I dont care about having my whole car shake and getting heard down the block.
