2 15" dc xlm2 in a 4th order

Im trying to figure out what i should tune my ported section i used 2.75 cubic feet per sub for the sealed portion and im doin a 2-1 ratio thanks guys

2.75ft3 per sub is too much airspace on the sealed side for XL 15s. If you were running 18s, maybe, but too much for 15s. I would recommend 1.5-1.75 sealed per sub.

Thys even better cause now i might be able to get a 3-1 i was told by a buddy who talked to jeff from dc and he said that 2.75 per 15 is best but the level 5 is less cause more motor force but do u know what i should tune the port to? I want low like 25-45 in range if possible

Jeff who? I wouldnt do over 2cu for a 15 period. But I'd suggest 1.75 for the xl 15s
