Query: kicker cvr 2ohm DVC

PLEASE READ:these subwoofers are absolutely awful! i decided to get them after reading countless numbers of wonderful reviews on amazon; however, it was a terrible mistake. before even putting the first one in, i hooked it up and it sounded terrible free airing. after putting both of them in a slot ported box tuned to 35 hz they made hideous humming noises which were awfully annoying. before these, i had walmart dual brand subwoofers that were 30$ a piece and they hit way harder than these things at a lower gain level.BUYER BEWAREE.
