Closest specs I could find to my speaker

Fb (Box Tuning) 35Hz
F3 (-3dB Cutoff) 29Hz
Pe (Watts-Rms) 150-425

I put these specs into www.bcae1.com/spboxnew2
I found my trunk has a gross volume of 9 cubic feet which is one foot less then the recommended build. I need help with the box design if its fine going one foot under recommended if not i need new ideas. Any help would be greatly appreciated.

They'll do fine in 6 cubes ported, i preferred mine sealed in 4.5 cubes. make sure you build the box to fit or build it in the trunk
