My box for my avalanche is 3.0 at 30hz which is about as big of a box i could figure out that would give the sub a good amount of port area and i would be sure would fit in the trunk. a matter of fact i still had to cut off some metal to get it to fit. I had this idea, why not build a five sided enclousure thats 12"x12"x6" or .5 cube internal, cut a hole to fit it in box(12"x~13.5) and make a "volume extension". it would make the enclosure a much more optimal [email protected] its would only be 3/4 inch too long for a exact 28hz tuning.
