no offense, but i know for a fact you aren't hitting 150db. i've got 2 12" Crunch's in a bandpass box in my little hatchback stang and it hits around 130(i was also on a budget when i bought them). I also have about 20ft of dynamat in the hatch too.
$1000...you gotta be shittin' me. You can get a lot better stuff that hits harder, sounds better, and is built tougher for less than that. If you wanna actually sell the stuff, take the price down a lot! Not makin' fun of your system, but for real...it's not gonna sell.
