Halostryker Posted March 15, 2013 Report Share Posted March 15, 2013 When I first bought my 2004 GMC Sierra Ext Cab, my first thought was how the hell am I gonna put a decent setup under my rear seat. First I bought a sealed box to fit two 12" kenwood subs, (the only subs I had shallow enough to fit) to give me a little bump in the mean time tell I could come up with something louder. My one goal was that I did not want to sacrafic my seating space, and to make it extremely loud. The only thing I could think of was to do a 4th order blow thru bed box. The equipment I have currently is a Skar Audio VVX 12 and a RE Audio DTS-1000.1 powering it. I plan on purchasing another vvx 12. the box I came up with has a sealed side of 2.77 ft³ and the ported side a gross volume of 5.26 ft³, net volume of 3.58 ft³ and tuned to 44.74 Hz How does this design look? anything that would make it better? also how should I go about sealing the blow thru off from the elements Thanks Link to comment Share on other sites More sharing options...
CleanSierra Posted March 15, 2013 Report Share Posted March 15, 2013 Tuned too low for a 4th in my opinion. get it in the upper 40 Hz range if it were me Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...

CleanSierra Posted March 15, 2013 Report Share Posted March 15, 2013 And why the deflector/loading wall you have in front of the subs? Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
Halostryker Posted March 18, 2013 Author Report Share Posted March 18, 2013 And why the deflector/loading wall you have in front of the subs? It was the only way I could fit that long of a port in the box, without hitting the magnets of the subs Link to comment Share on other sites More sharing options...
