How can I change the internal volume (want to make it smaller
)of my box with out rebuilding it?
How much different does using 8ga speaker wire make over 12ga?
I build a box that I really like. But I think I can get more out of it. But I don't know alot about testing. I got 147.5 @2900 watts on the dash and 150 flat in the kick at the Nspl show yesterday. I was playing around with it today and gat 148.6 on the dash and 152.3 out the kick. The Setup is 4 inverted 12" Hifonics Burtus being push off a Sundown 3k @.5 . The subs are inverted because the 2 outside 12's won't fit (to deep)in the box. The box is 7.5 cuft after displacement & tuned to 40hz. I hoping you guys can give me some tips on how to fine tune my setup. I will be changing the subs to Sundown sa-12 went my money get back right.

there is always plenty of things to try to find gains! shoot me a PM with all of your information and lets work from there to srr what you can do.
