SPLadd1ct Posted April 4, 2014 Report Share Posted April 4, 2014 BTW ratio doesn't mean anything, it's just a guideline....individual volumes matter, not the ratio. 2011 Ford Ranger Sport 4.0 v6 2 sundown audio prototype nsv4 15s crossfire 4k wired to 0.4 ohm 15 banks of maxwell 3.0 caps @ 18v triple alts (x2 us alt 250's, x1 singer 320) 153 at 23hz Link to comment Share on other sites More sharing options...
CleanSierra Posted April 4, 2014 Report Share Posted April 4, 2014 BTW ratio doesn't mean anything, it's just a guideline....individual volumes matter, not the ratio.I agree with this^^^Volumes look like their on point too and a good baseline for where I'd start too. I'm in process of designing a bandpass 4th wall for 4 15" XLs. Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...

john253a Posted April 4, 2014 Report Share Posted April 4, 2014 Its at 68 sq inches of port area. Is that for 1 sub or both subs So is it 68 total or 136 total Link to comment Share on other sites More sharing options...
CleanSierra Posted April 4, 2014 Report Share Posted April 4, 2014 I think what he has John, is a box with 3 chambers. A sealed chamber on each side and the subs firing into the common ported chamber. He's running a blowthrough so I'm going to guess he just had a single port into the cabin. He's got a blowthrough in a Honda Ridgeline I believe. Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...

detroitdb Posted April 8, 2014 Author Report Share Posted April 8, 2014 So build is in full force! Using 3/4 inch birch x 2 screwed and glued together. Baffles will be 4 layers screwed and glued together! Btw I have not been able to post pics in a long,long time. Is there some kind of settings on my computer that might have changed? And I usually use photobucket to upload pics https://photos.google.com/photo/AF1QipP7rjav9cD9UFdAYBJmz4M4LoNlF26ng1xhAf4Uhttps://photos.google.com/photo/AF1QipP7rjav9cD9UFdAYBJmz4M4LoNlF26ng1xhAf4U 2013 DODGE CHALLENGER R/T SUNDOWN ZV4-18 CRESCENDO 3.5K PIONEER AVIC 5300 NEX ALPINE TYPE R 6.5S & 6X9'S ROCKFORD FOSGATE 1.5" TWEETS 5 C&D TECH BATTS Link to comment Share on other sites More sharing options...
