I am looking for any help with building a slot ported box for 2 type r 12"s in a 2000 grand am. I wanna try to keep it a small as possible to keep trunk space availible. I had a custom box built for my explorer and it slammed but is way to big for this vehicle- anyone have any plans already done up? I built a 2 part sealed box(a slanted truck box right up against the seat with a rectangular box attached to it) but it just wasn't loud/low enough for what i'm used too
Anyone wanna help me?

thanks

a truck will def hit better than sedan with a trunk straight off, the upgrades begin

i know and realize this!!!
