i'd go around 8cf tuned to 35hz, that should get pretty "loud".

using those measurements it would be around 8-8.5cf, so using 2 8inch ports, 21inchs long would give you a 35hz tune with 100sq inches of port. http://www.bcae1.com/spboxnew2.htm heres a link for help with boxes.

yep just like that, if you need ports talk to cannan he makes flared ports and sells them, or just buy some 8inch pvc pipe.

just make sure each sub gets @ least a 2cuft after displacements - tuned 34hz would slam ......

using these measurements " 32"L X 37"W X 17"Tall" i get 8.19cf net after port and speaker displacement, and using 2 8icnh ports 21.002inchs long would give you a 35hz tune with 100.553sq inches of port area. so that would be 2.7cf per sub, i think that would be perfect. and if you think my calculaions are wrong check this site http://www.bcae1.com/spboxnew2.htm go down to where it says ported enclosure and enter all the measurements.

well i just checked dustin\remembered that i won't have enough room to put 3 subs and 2 ports on one side so what if i had the subs on one side and then the ports directly behind them??
lyke this>>> w\ subs fire'n into my car?? or would it be louder w\ ports firing into my car???

ya that would work, but i'd recomemned having the subs firing up and the ports firing back, but either would work.
