i took out my back seat, theres nothing between my trunk and the inside of the car now, it actually dosent look that bad, ill post pics tonight. theres a HUGE diffrence in SPL, im guessin 2dbs or a little more. my plan is to get that hole cleard off and build a wall and put the 4 subs across where the hole is. if i do that should i just mount the subs on the wall and use the entire trunk as a box, or build a box that spans across the opening that looks like a wall, but is enclosed on all 4 sides? i think yall will get what im sayin when i post pics, anyways.....let me know.
