the cvr will bump if in the right box go ported if you can running 2 cvr 12s 2ohm with a 750.1 kicker like you got hit a 138.3 spl low was 136 something that was in a bad box. i would recomenting a ported box will make it get louder just my 2 cents but i dont really know alot and i dont thing a 750.1 can run 2 cvx 12s in my opinon.
my subs where working fine befor i remove them i put them all back and i got a horrid noise comeing from the back. its late to night so i really couldent look at them. but it sounds like metal radlling but not exatly do subs make that noise. it all most sounds like there blown but still pound. idk its late got my car all back to geather lets hope all is good and its just something lose right....
yes i will bee at the eppin show in october. i think i might show up tomorrow but i only got my head unit and door speakers in right now. for the box well it was the victom of me getting really pissed off and a ten pound sleg. that box has gone to the box heveans starting from scrach.
