[QUOTE="TheGDog, post: 7003680, member: 626170"] Dude... yes... it is DEFINITELY your box that is the problem. I have a 1.8 cu. ft. box ported with like 36Hz and the port is 4" diameter and something like 12.5" long. I can't see a 2" port of ANY length doing more than making lots of what is called "chuffing" noise for you. (Noise made by air turbulence cause by the resistance being to high in that port for the amount of force of air that's being pushed thru it. [URL="http://www.the12volt.com/caraudio/boxcalcs.asp#frac"]Subwoofer Enclosure Calculators, Fraction to Decimal, Parallel, Series, Port Length and Volume Calculators[/URL] Has the calculators you'll need to properly figure out your boxes Internal volume... and the calculators you'll need to help you figure out the port diameter and length ( for round ports ) and another calculator in there to help you figure out slot ports as well. I'm using a lesser amp than you... a HITRON HA-1000.1 (600 W RMS @ Ohm... supposedly) and it BOOOOOMS!!! [/QUOTE]
