2 15's or 3

[o8mustang13]

ok we are still talking about doing the two 15 with the four amps right and a total box volume for both subs being 6 or 7 cubes or 6 or 7 cubes per sub??

also with the port being 17.31 x 4 x 6.53 isnt my port 452 cubic inches?

Im designing a wall similar to Twisted's in my 2010, and we're right around 13 cubes. Wall that shit. For 3 15's.

port area is measured by the port width and height, not depth.

2 15s, 4 amps, 6 or 7 cubes for the pair

how many cubes would you say for the three 9 or 10

yea, around that, but then youll need to account for port volume and sub displacement too. not enough room from you measurements you already put

the measurement i put the first time are using 1" MDF if i shrink that to 3/4" minus sub and port displacement i get 11 ft3 and using the 3/4 i will fiberglass the box with 29 oz mat to compensate for the thickenss and also the front and top of the box will have a secong sheet on those to flush mount the subs a little bit.

edit: with sub displacement i have 10.28 ft3 have yet to calculate port

Do 2 15s in 8 cubes net with 130 square inches of port tuned to 35hz. WANG.

I was hoping to get it tuned to 30Hz

[fritosaregood]

you could go down to 3 cubes per sub, if you want to do 3 subs. but make sure you can have a good size port too.

also, dont just brace you box with sheets of fiberglass, you need some threaded rod or some other kind of cross bracing
