I got a max height of 16 x 34w x 32 Depth. I did leave room in these figures at-least a few inches so the box would slide into position. I would like to shoot for something that will let someone outside my car feel my bass when i drive by. As for anything else thats where me lacking experience comes in play. The last system I had was back in 98-99 when I ran 6 entry level ppi on a single 500.2 in a pontiac sunbird. Always been a rockford fanboy of sorts but seems their is so much more in terms of great product now. This is why I am shopping around for subs.
