Mrbubbles00482 Posted June 11, 2009 Report Share Posted June 11, 2009 Ok need some help. Max dimensions are 42 wide 10 tall and 12 deep. So 2.1^3 feet gross. Ported I wanna do external ports through the rear deck. I can do 1 4" round port for 39^2 inches of port area. at two cubes i need like 32^2 inches so that works out. Calculating frequency though, all my programs and the12volts calculator does it for internal port. Any help? Quote Link to comment Share on other sites More sharing options...

Jville140db Posted June 16, 2009 Report Share Posted June 16, 2009 (edited) so if you want to do those dimensions you would need at least an 8in port to get into the 30's and that would be 38hz if you only have the 5in to work with you will end up with about 44hz hope that helps Edited June 16, 2009 by Jville140db Quote Car is 2010 Scion Tc Currently in car Deck- Sony XAV-60 in-dash mobile video system Speakers- Rockford Punch 6.5in comps in the front and coax in the rear Subs- 2 Gen 3 Rockford P3 12's dual 4 ohm Amps- Rockford P1000-1bd and P400-4 Alpine Mrp-f300 is in for P400-4 which is out to service Wiring- all rockford nuff said Enclosure- Dual 12in custom box by SRQ Battery- Optima Yellow top with big 3 done Sound Damping- All Dynamat products 1-2 layers throughout with liner on top Link to my build log- http://down4sound.co...=newpost&t=5275 Link to my youtube- http://www.youtube.c...ser/Jville140db MECP Advanced CEA # 110531 BassBox 6 Pro for Box Building/Re audio box calculator If you can hear the passenger it aint loud enough!!!!!!!

tibs Posted June 16, 2009 Report Share Posted June 16, 2009 isnt a 4 inch port like only like 12.56 sq inches so youd would need like 2 or 3 of these ports. or you can probably get away with 1 6 inch Quote Tibs 99 F-150 Build 8 twelves 8 - Re SE 12"s 2 - SunDown Audio Saz-3000d's 1 - vx4004 planet audio amp big 3 1/0 gauge MECHMAN 250 amp alt MySpace Link to comment Share on other sites More sharing options...
BulletInjection Posted June 16, 2009 Report Share Posted June 16, 2009 isnt a 4 inch port like only like 12.56 sq inchesso youd would need like 2 or 3 of these ports. or you can probably get away with 1 6 inch 22.5 in tall so its 90 inches of port area which per ^3 foot for my sub is 12in-16in so its about right? I think? wth idk I am in no condition to be making these decisions right now Quote My build: http://www.stevemeadedesigns.com/board/ind...8920&st=100 http://www.youtube.com/Bulletinjection Link to comment Share on other sites More sharing options...

tibs Posted June 16, 2009 Report Share Posted June 16, 2009 (edited) 22.5 in tall so its 90 inches of port area which per ^3 foot for my sub is 12in-16in so its about right? I think? wth idk I am in no condition to be making these decisions right now port area people normally refer to doesnt even matter what the length is. 1 4 inch port is 12 sq inches 2 cubes should get around 30 sq inches. port volume matters with the sq inches x port length Edited June 16, 2009 by tibs Quote Tibs 99 F-150 Build 8 twelves 8 - Re SE 12"s 2 - SunDown Audio Saz-3000d's 1 - vx4004 planet audio amp big 3 1/0 gauge MECHMAN 250 amp alt MySpace Link to comment Share on other sites More sharing options...
