Alright, I'm fixing to be putting 4 12's in the back of my truck and have it ported into the cab. Each speaker calls for 2.0/3.5 feet of air space and the size of the box cant be any wider the 41"....taller than 15" and longer than 36"( i could go longer if i must). I'm wanting to make the subs in a V shaped box cause I figure that would sound the best. Is anyone willing to help me with these box demensions. I'm at a loss

with those dimensions you have about 2.5 of air space per sub.

Alright thanks............i'll have 2 on one side and 2 on the other (of course haha) so would I just have a wall seperating the two sets? Do you think 4 soundstream 12's would sound bit harder than two soundstream 15's? I think it should.

that would work fine.. 4-12's have more cone area than 2-15's . brace the inside of the box well. each brace you add takes away cubic inch. what line of soundstream sub are you using???
