fox_racin4 Posted June 9, 2011 Report Share Posted June 9, 2011 in my experiances with these extd cab chevys, they LOVE the lows.. i was tuned to 38 and was peaking around 28. when i was tuned to 34 i was peaking in the low/mid 20s, i am now tuned to 41hz and can play down to 29hz no problem. Derrick, his box is really.. messed up you could say, the port is 5" wide x 18" deep then when it bends bends ( L port) its 3 1/2" wide 21" long he had a shop build it for him, before he fixed his port the port opening was 5"x17 1/2" but had like.. an oval over lapping port opening becasue the shop said " it throws more air around" Quote 1998 gmc extd cab 12 crossfire C710s 4 SAZ-4500s 3 Singer 400A altsbuncha mids/highs Team Asshole Link to comment Share on other sites More sharing options...

Team_DC-Derrick Posted June 9, 2011 Report Share Posted June 9, 2011 your height of the port from the top of the box to the bottom of the box *the top and bottom of the side your subs are on... is 18.25 right? basically, how tall is the port, we got the width and length... if anything, i would cut it down right where it bends at.. if your height is 18.25 and 5 width, and with 18 length, you will have 16.47 sq inch per cubic foot.. tuned to 41hz Quote The DC Integra 3 18s to 6 15 build log Team_DC-Derrick's Youtube Team DC Audio where theres a will theres a wall.......

fox_racin4 Posted June 9, 2011 Report Share Posted June 9, 2011 Yes 41hz sounds high but it will peak around low 30s , like i said im tuned to 41hz right now and can still play down to high 20s no problem, these trucks like the lows, and subs forward port up Quote 1998 gmc extd cab 12 crossfire C710s 4 SAZ-4500s 3 Singer 400A altsbuncha mids/highs Team Asshole Link to comment Share on other sites More sharing options...
