Box Design

I am going to put my money back and when i have enough go all out on a system. So right now I was wondering if there was a freeware program that i could use because i basically only need one box built and dont feel like buying something i am only going to use once. If not could someone provide some specs for a box? Its the older kicker comp 12 inch... i dont know the specs until i get home.

coulda just googled it, there are a million places.
if you want something more complicated for that kicker other than just a sealed box, someone here would design one for you for a small price.

I'll design you an enclosure. It'll be more accurate, and list all full specs, dimensions, a cut-sheet listing the exact size of all pieces needed to construct the enclosure, and a sketch. $10...

Same here, as ngsm. Although I charge $15 for more in-depth enclosures.

Actually I was thinking about selling the 2 12's and getting 1 12 or MAYBE a 15 for trunk space but i dont think it will help due to the face that a correct box will be just as big... i was leaning towards the RE XXX but suggestions anyone?

build an isobarik. 2 driver, about half the space of one. only thing is, your 2 drivers will be acting as one, but you should read up on it, there are ups and downs to every setup.

isobarik will use half the space, but also play 3db lower.

hypothetically:
1 RFP 12 plays in 1ft^3 at 120db @500W
2 RFP 12's isobarik play in .5ft^3 at 117db @500W

To get the iso's to play as loud as the single, you'd have to bump it up to 1000W.

On the up-side, the iso's will play lower, clearer, more defined, less distortion.
