What is the difference in SQ and SPL with a shallow but wide box(behind back seat) or regular sized box(that you put in your trunk)?
thanks

are you talking about 2 sealed boxes with the same volume? if so there is no difference.

The truck boxes look like they are smaller then the ones that go in ur trunk they kinda are. but not by much.

See the box is the same no matter how it is shaped.

well as long as you have like 2" for the vent hole, i suppose it doesnt matter.

they are both sealed boxes. the one behind my seats sounds like crap when the seat isn't there(2 subs). the one for the truck was set on my back seats and it sounded really good.(1 sub) ???

thanks

but i thought air space was air space? i just want the best sound out of my subs and figure how to make a better box for behind my rear seat. i have a 02' f250 super duty crew cab and took the demensions from the single sub box and tried to match the airspace with my custom box. my box is 8" deep on bottom, 6" deep on top, 57" long and 15" high. i am using 5/8 mdf. it is a really long box. i am thinking of making it shorter but taller. any suggestions?
thanks

it sounds better when it is behind the seats because the seats dampen the sound....thats all there is to it, its just the way the acustics of your car work
