Menace89 Posted July 13, 2008 Report Share Posted July 13, 2008 I just finished building my wall for 4 15" DC lvl 3's and it doesn't hit. Im pretty sure my calculations are right but if someone can check em that would be great. Inside box dimensions: L- 43.25" H- 32.21875" D- 18.75" Total= 15.12 cu. ft. Sub displacement= 0.88 cu. ft. Brace and 45's displacement= 1.2536cu. ft. Port displacement= 0.375 cu. ft. = 12.6114 cu. ft. net 3.15 cu. ft. per sub Port size= 12"x12"x5" I am running the subs off of 2 Cerwin Vega 1200D (2subs to 1 amp) wired to 1 ohm. Any help would be greatly appreciated. -Thanks Quote Link to comment Share on other sites More sharing options...

Stephen Posted July 13, 2008 Report Share Posted July 13, 2008 im only getting 12.8 cu ft before displacement. he said they are inside dimensions not outside Quote you can cook bacon shirtless if you're not a pussy...lol not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.

sonic purity Posted July 13, 2008 Report Share Posted July 13, 2008 I think you will need more power than those cerwin vegas. Just my two cents Quote n2caraudio.com Link to comment Share on other sites More sharing options...
Menace89 Posted July 13, 2008 Author Report Share Posted July 13, 2008 the lvl 3's are only 600 watts rms...I had 2 12" Cerwin Vega V-max's on one of these amps and they sounded great and they were 600 rms as well Quote Link to comment Share on other sites More sharing options...
sonic purity Posted July 13, 2008 Report Share Posted July 13, 2008 did you double check that none of the coils were out of phase. Still think you need more power than that. Quote n2caraudio.com Link to comment Share on other sites More sharing options...
Jcoleman134 Posted July 13, 2008 Report Share Posted July 13, 2008 have you checked the gains and everything. because i know some people including my self have forgotten to set the gain before lol Quote Link to comment Share on other sites More sharing options...
Menace89 Posted July 13, 2008 Author Report Share Posted July 13, 2008 Ive checked my wiring like 5 times and ive even rewired them with 12 awg wire so that the whole wire would fit into the terminal...and when there playing they all look like their moving the same Quote Link to comment Share on other sites More sharing options...
sonic purity Posted July 13, 2008 Report Share Posted July 13, 2008 try turning off each amp and running just one to see if there is any difference in output. Quote n2caraudio.com Link to comment Share on other sites More sharing options...
