Best port placement for crew cab truck??

ok, tried the 90's and did basically nothing?? Seemed to hit the lows a bit better but that's because it made the ports longer. I am really not getting it, my brother in law has a escalade with a Incriminator audio death penalty 18 and a Hifonics 2608 that BRUTALLY KILLS my setup and I have over 1K watts more than him in a smaller cab? I really don't know what to do here, should i just scrap my nice box and start over? Here is a pic of my build... 4.33 CF 40HZ three 4" aeros and CRAP for bass!! Moth%$ F@@#%r!

Really? I asked like 20 people on here if three 4's were good, nearly ALL said yes??? You think I need one more? Aeros are supposed to be worth double that of a slot I thought?
