down towards the bottom of teh page are frequency response diagrams of different enclosures..

i figured id go with a sealed enclosure.. what air space would be best?
thanks

 

For SQ you would want a Qtc of .707...according to that chart, the closest would be 2.0 ft^3 each.

But...since that isn't considered a SQ sub...the 1.0 ft^3 should do you fine.

 

what if i went witha "provent" where teh MDF wraps around the sub?

like this, but not the square subs..

im just looking to hit hard and clean..

 

yea between 1- 1.5 cubit feet per sub. If you want tight hard bass, sealed is the best way to go.

Or you could try buying this box,

your not going to have room under the seats for a proper vented box.
