help with two 05 alpine type-R 12"s

[b_mcdonald3]

I just bought two brand spanking new 500 RMS type r 12"s and a JL 1000/1 to slam them.

I wondering if anyone can score me some dimentions for a slot ported box for them.

also would it be better to have a sealed or ported box for inside a hatch back car that is missing the back seat ( in the open car visiblly behind you )

thanks,

mcdonald

its kind of hard to say we need to know who much space we are working with and what you want to tune your subs to(if you want ported).

Well I got 1 alpine Type R in my little neon in a 3 cube box tuned to 33hz. I still got a little bit of room, so im guessing u could get at least 2 cubes per sub. But anyways I used to run my Type R sealed. Ported it sounds much better.

My peticular specs, tube port....

External measurements: 33 x 15 x 15.844126984126982

Desired internal volume: 3.53 ft3

Thickness of box material: .75 in

Displacements: 2 3x3x3 boxes 0.015625 x 2 = 0.03125

.75 x 15 x 15.844126984126982 = 0.10177651014109346
