rboudreaux77 Posted May 17, 2010 Author Report Posted May 17, 2010 i was also wondering how do i know how much port area is enough? what determines how much port area i should have? http://www.dcsoundlab.com/ 2008 Chevy Impala (Daily Driver) Pioneer touchscreen w/navi 1 DC XL 15" (around 4cuft ported box) 1 AQ2200 1 AQ90x4 Memphis MClass 6.5s (front doors) Memphis MClass 6x9s (rear deck) stock alt & front batt; 1 Red top in the trunk 139.2db sealed (on my old JL1000/1) 140.0db outlaw (on my old JL1000/1) 1992 Chevy S-10 Ext cab.

skittlesRgood Posted May 17, 2010 Report Posted May 17, 2010 12-16sq in of port area per cube, after displacement. since its in a trunk, if you fire everything forward and seal off the trunk you will notice a big gain. If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

kmalinich Posted May 18, 2010 Report Posted May 18, 2010 i thought about that but then i would lose my backseat cause i would have to leave the seat down all the time right? if your seats fold down you wont lose it... and if you think about it, you don't really play the sub full out when the car is packed full of people (usually) so it's alright... and if you follow the 12-16 rule you'll be fine.. i built a box for an RF T2 15 that was 3.48 ft3 after displacement and it had over 50 in2 of port area...
