Hey guys,

Have a 12" Punch HX2, looking to build a ported enclosure for it.

What would you recommend for port area, tuning and box size for a single 12" HX2 that will be getting 400rms. Going in the back of a my friends civic coupe.

I was thinking 1.8cuft, 30 square inches of port area and have it tuned to 39hz.

Since he doesn't much power should we go with a bigger box to get the sub moving more?
