[QUOTE="East, post: 8686167, member: 644796"] SETUP: 2 FI BTL NEO 18's WOLFRAM 4500.1 @ .5 OHM (4) XS 3100's Mechman 320 (voltage stays around 13.5-14v) 04 Yukon SLT BOX: 12.5ft^3 (4) 8" AERO 22" (200IN PORT) TUNED 36HZ 4" FROM HATCH So my system slaps the lows nice but that seems to be about it... I'm not very happy with it and I feel its the enclosure, my single 18" seemed to hit highs much better. I was told more port area was good for numbers so I went with 4 ports and figured I'd plug one for daily. Well... my system only hit a 148.1 and I was told by many a 150 should be EASY with my setup.

Is my box too close to the hatch? why am I not hitting highs when tuned to 36hz? is my hatch acting as an extension to the port lowering tuning? how far is optimal distance for my configuration? I want to build a new box to achieve a 150 but I don't know how to hit the highs any better, even at 36hz tuning a 40hz tone seems very quiet, but if I play 32-36hz my car falls apart from the lows.
