[QUOTE="ejschultz, post: 6002524, member: 603800"] the thing is in the manual for the subs, the minimum ported box size is 1.75 cubes per sub. at that size they'll only handle 300 RMS. i think my box is smaller than that. basically, i had the 05 cvr's in the kicker box and i purchased 2 cvx's to take the cvr's out. i'm using the kicker box. the cvr's say the same for minimum size, but the power rating doesn't change from the smallest size to the largest recommended size. with the cvx's, it changes from 300 each to 700 each, smallest to largest recommended size, respectively. i'm only using an alpine mrd-m605 for the subs (dual 2 ohm wired for a 2 ohm load) so i'm giving them 638 watts rms, according to the birthsheet that came with my amp. i'm afraid i'm going to mess them up if i keep playing them with that kind of power going into them in that small of an enclosure. also, my subsonic filter is set to 15 hz 24 db/oct slope. the subs are rated with a 25 hz subsonic filter with a 24 db/oct slope. i've only got 15, 30 or off. with it at 30, i'm missing out on a lot of low stuff.
