Story of my truck goes like this, I bought it new late in 2006 when i was still in high school, Got a 6 inch lift 2 weeks later with 35 inch tires, Installed a kicker solo x 10 sub that fit under the back seat, had that for a couple years until it was stolen out of my truck, i replaced everything with jl audio amps and a 13tw5 sub that i got a deal on. In may i decided to redo my entire system focusing on sound quality.
I bought an MB Quart fx 1.600 Amp to power two kicker l7 8's in a down firing box, and a MB Quart Fx 4.100 amp to power my components. Up front i with with DLS 6.3 components, and in the rear DLS 4.2 compents. At the time I had no Idea how loud my components would be, I was blown away. The two 8 inch subs were not bad either but I wanted something with a little more thump.
Currently I am waiting for two Kicker Solo X 12's and a zx2500.1 amp in the mail (comes on the 8th), so I downloaded the manual and have begun building a New Box and it is a monster! It is 12.6 cubic feet including the port displacement and 58 inches wide. I am half way through building the box, waiting for the glue to dry on what i have done so far. Hope to have everything installed in a weeks time.
