i have one MTX 12" sub in a Q logic box. it takes up more room than i like, but the problem is that when the top is off it would be pretty easy to steal the thing. i want a way to keep it theft proof and water proof. right now i have a box that covers and conceals the speaker box. it is open in the front so the sound is great but i think that when i put in the seat it will muffle the sound. any way around this? or will the seat not cause too much problem.
