hows this look for a 15'' 187

[rosshimself13]

right at 4 cubes gross 3 cubes after displacement, 12 sq inches of port per cube gives a 4.5X8 inch port just under 26.5 inches.. going in a girls suv with port up sub back... on about 500 watts..

actually my math was off, had to make it 1 inch deeper to get the correct volume and make the port a half in narrower to compensate for the height.. but the other demensions are left the same.. 20X36.5X10.5 now..

We dont really have a clue what youre trying to do with the enclosure. What kindof sound does she like?

If IA's specs are correct, it'd rather be in a sealed or 4th order bandpass box. Ported will give you good output, but unless you go with a large low tuned box, it's probably going to be rather peaky and seem to lack low-end in a small-ish ported box, like what you're wanting to run.
