just some older Kicker Comps.
If you want ported I'd go with between 3.5-4.5 cu ft per sub

Yea, im not sure of the exact model they are. he just bought them off somebody for 100. they drill tho, he has them in just a standard ported box for 2 15s. we already have the shape for the box from my old box with 3 12s. just took the front off of it. now i curved the sides and i was just wondering about each chamber size. you think that they might know if i just called kicker?

im thinking about going with around 2.5 cubes per chamber and brace it with some threaded steel rods with the nuts on it having loctite on them to keep them from rattling loose, how about a port size and a tuning frequency?

2.5 cu ft is way too small to port these.
atleast 3.5 cu ft each. 2.5 cu ft would be crap for ported. Sealed I could see that.
