Nightshade Posted March 23, 2009 Report Share Posted March 23, 2009 How big is each chamber? Also yes I would add another 1 or even 2 4" ports for each sub. I have 3 4" aeroports for each 15" in my car. I would say that 3 per 18 will work much better and be louder. The only thing is it will tune the box higher. Let me know how much airspace you have and I'll tell you how long to make the ports to tune where you want. If it were me I'd tune it to 37 hz. 2013 VW Jetta GLI 2.0 Turbo 1 Sundown Audio SCV2000 1 Sundown Audio X15 V2 1 XS Power D3100 Audio Control LC6i Stock Deck 146.4 sealed on the dash at 37hz 2001 Focus ZX3: RETIRED Team Sundown Audio, Team XS Power, 2 time NSPL Car 3601-Up Champion, 2 time NSPL Car Hardcore ChampionHighest NSPL Scores to date:154.3db on the dash sealed at 46hz, 156.2db in the kick at 46hz155.2db unofficial on dash at 43hz Link to comment Share on other sites More sharing options...

Here r the numbers 60X24X20 thats around 9^ft per chamber. The other 4 ports are 18 so i guess i should do 2 more @ 18 one in each chamber. Man the box hit so hard i shook the coffee in our local wawa the manage came running out and said can u not play ur music that loud until he saw the uniform HA HA HA lmao.

Nightshade Posted March 24, 2009 Report Share Posted March 24, 2009 Add two more 4" ports per chamber. Make each of them 18" long and that will tune the box to 32hz. If you want to tune higher your going to need to cut some length off of the ports. If you want to tune to 37 like I reccomended you'll need to make the ports 12.25" long each. I reccomend that you definately do at least 2 more ports per sub, so a total of 4 more ports cause if you only do one more per sub you'll be tuned at 28hz with them at 18" long. 2013 VW Jetta GLI 2.0 Turbo 1 Sundown Audio SCV2000 1 Sundown Audio X15 V2 1 XS Power D3100 Audio Control LC6i Stock Deck 146.4 sealed on the dash at 37hz 2001 Focus ZX3: RETIRED Team Sundown Audio, Team XS Power, 2 time NSPL Car 3601-Up Champion, 2 time NSPL Car Hardcore ChampionHighest NSPL Scores to date:154.3db on the dash sealed at 46hz, 156.2db in the kick at 46hz155.2db unofficial on dash at 43hz Link to comment Share on other sites More sharing options...

Currently have 2, 4inch ports per chamber @ 18 inches long. So what u are saying is add another port for each chamber 4 inch abs @ 18 inchs. The only thing is I only have room for one more port. http://www.stevemeadedesigns.com/board/public/style_emoticons/default/mad.gif Hope i don't need more.
