thanks, I see that it is 4.5cuft 32Hz I will let you know when I have finished

ok, I would go without fail. now you have the maximum size of my box (simple or not ... never mind) Whereas I like the deep bass, can I have a box design?

nominal impedance in amp is 0.7ohm ( btl is dual 1.4ohm )...i've 2 fam80 spl but this amp is super efficient. So what's the solution?

yes...sorry

I'm in Calabria. referring to the drawing, the max external dimension for the box in my renault clio III R are: a: 26 c: 17.28 h: 13.59 alpha:61.8° beta:79.4° box lenght: 37.82 port and subwoofer should be on top in "c" for the simple box external dimensions are: 17.28 x 17.28 x 37.82

??? help me
