what size are those subs? and what size port? 3 also have you considered upfiring?

Attachment 20689

the RFs? 15s, 4" ID port(forget the length)

i find upfiring in a trunk sucks lol but ive never tried ported upfiring before

or how about subs firing up and port firing into the cabin!! ?

2-4inch ports? interesting i don't see a flare on those lol!! but for 2-4's wouldn't you use those for 2-12's? or would you need more port area? i could be wrong

seats dont fold down

ya no flare, ghetto PVC piping lol i went with what the RF manual said

lol ghetto fab!! ftw lol!! maybe step down to 2-12's would be a better fit?

ya a couple people think i could be louder with 1 15 instead of 2 in a small box, im gonna see if i can get a box through the rear seats(gotta remove them), i might have to trim some metal but if it works i could probably do 34x15.5x35 which would be 8.8cubes

if the box is too small(internal volume is what we care about) for 2 15's then you may very well be louder with going down to just 1 15" but using a larger box e.g. 2 15" in a 3.0cuft box or 1 15" in a 3.0 cuft box. if all things were equal the single sub set up would most likely do better

34x15.5x35 NICE

if you can get those sizes you can use my box design!! and while you are at it if you can get that much cubic you might as well toss some nice subs in there that will pound!!

like Fi or sundown (a kid on here is selling some i think)
