ok im gonna use 2 15" mofo's in the back of my 95 lumina, anyway on the spec sheet it says n/a under the dimention size for a sealed box, does this mean that i cant use a sealed box? and if a can use one which is better for the SPL and SQ, a sealed box or a ported box?

Sealed box is good for cars with limited trunk space. If that is not your problem, then go ported. It'll give you higher SPL.

Isaac is right and plus you cant really tell which will sound better because, it depends on how good the box was built, and your personnel opinion.

yea i agree. i think a ported box is better than a sealed enclosure. use 1" mdf and batton. or better still 1" plywood and batton. this builds a truely solid box

the EBP is probably too high for a sealed box, so it's not recommended.
go with ported anyway if you have the space.
much better overall results in my personal opinion.
Especially for fifteens.

"plywood is a nono it flexs to much."
Actually, plywood is stronger than MDF. It's stiffness makes it more resonant, though, that's why it isn't as ideal. It doesn't damp as well as MDF.
