Ok I am going to go out this weekend and get all the MDF I need to make a box but I'm stuck on what I should get. I am leaning towards getting 1 15" in a vented box. No matter what size it is going to be a Kicker Solo-Baric L7. I am thinking about building a 4.5 cubic foot box which is pretty big. The trick is I can't build it and then put it in. I would have to actually assemble the box while it is inside my trunk. Has anyone tried this? It would be a good theft deterant since you couldn't take it out though. I am also debating on the Kicker KX600.1 amp (Around 800 watts) or the Fosgate 1001bd. The 15 can handle 1000 watts RMS and I think one is all I will need to pound hard. Please give me some feedback on what kind of amp you would recommend.
