Has anyone with a 5th gen hacked away at the center portion of the rear seat so they can have their subs directed through the arm rest opening? I want better sound INSIDE the car without having to crank up the subs and make everything rattle. MDF is pretty cheap and I have all the tools, so I wanted to make my own custom enclosure with the subs in a "V" facing through the opening i'd have to make.

Just looking for possible pics and opinions... also, what would be a good thing to use to cover up the edge of the rear seat and carpet where I cut it out? I was thinking the black door edge trim from an auto parts store... ??
