parameters

I was wondering on my parameters at this site it tells me what size my box should be for best quality http://www.carstereo.com/help/Articles.cfm?id=17 if so how would i go by making the box i havent learned that well how to read the shit but im gonna take it down to a shop and get my box done i just got to have specifications

what sub do you have?
do you want sealed or ported?

i have 2 mtx thunder 5500 15's and im not sure i havent really had ported before but ive had sealed i just want what hits hardest and im not sure how ported hits

got something for you, to check out. maybe it'll help...

I would do 2.5cf per sub after displacements tuned to 33hz if you want ported, or 1.75-2cf each if you want sealed
