Kicker Comp 10", website says minimum is 1 cu.ft. I really don't have much space to work with (ranger) and have 1 sheet (2x4) of 3/4 MDF. I have the dimensions at 16w x 16h x 8d which gives me ~.8 cu.ft. The amp I'll have running it will be shitty to say the least (SPL rated at 180rms bridged) so will I be ok having less volume in the box?
