Max dimensions would help. Also how much power is available. And what is your goal? Strictly SPL or a daily driver.

Im going for a Daily Driver because I know I cant get 4 in a spl setup.... but the power isn't a problem I have two of the MTX AUDIO THUNDER ELITE TE4001D //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif so that should be enough power. and as far as dimensions I have

36x14.5x36

So sell those and do two BTL 15's:greedy:

15's are more realistic

if you can get a little over 8 cubes net, the 4 12's would work.

will that be ported or sealed

 

[delvryboy 5,000+ posts]

ported, that means 8 cubes(7.5 would be ok) + port and sub displacement.

Def ported, BTLs do not like sealed boxes period.

I thought about doing something like that, well thats the only way I could do ported wit 4 woofers anyway, but the thing is how big should I make it and what should I tune it to
