im45pl Posted June 14, 2017 Report Posted June 14, 2017 Since I have to rebuild my box due to a water leak I was thinking of going for a 4th order enclosure, question is what cubic footage would be required in the sealed section? Any info would be appreciated Quote TEAM DC AUSTRALIA My_Build_Log
rambronco Posted June 4, 2018 Report Posted June 4, 2018 I would say it depends on how much power you have going to it. If your going to running close to full RMS power to it youll want to keep the box on tbe smaller side 5 - 5.5 cu ft with whatever ratio you decide for the ported side. If the sub will be used gently make it a bit bigger if you have room 6 - 7.5 cu ft. Just remember that anything done on the sealed side needs to be changed accordingly on the ported side (bigger sealed means bigger ported side of you are trying to hit a specific ratio. Quote 01 Chevy Silverado X-cab 2 Sundown Z18v4 walled on 2 Lanzar Opti 7k's strapped at 1/2ohm = each amp wired to 1/4ohm. Havent checked impedence rise so not sure what they are actually seeing. 6 group 31AGM's. 2-Eclipse 34230's each one running 2 Eminence 6.5" Beta 6A. These are beastly mids rated at 350w program power. I was skeptical but the eclipse amps are 370w x 2 and when there was 4 mids on 1 amp I could push it into thermal protect within a song so added the 2nd amp. Eclipse 4212 running 4 CT sounds Meso tweeters. and 2 DLS ultimate tweeters up high to raise the soundstage. 96' Ford F350 4wd 4d long bed 7.3 diesel with 91k miles. Will be the sound quality rig if I can ever find the time.
