cj407 Posted October 7, 2011 Report Posted October 7, 2011 depends on desired tuning. with 4 of them i'd suggest 6" aeros instead of 4". imho 2 4" aeros on the 2 15's wasn't enough port area. https://www.facebook.com/pages/Cande-Shop-Llc/37897329949?ref=hl Youtube: http://www.youtube.com/user/Cande0Man"]http://www.youtube.com/user/Cande0Man
TheBetterMethod Posted October 7, 2011 Report Posted October 7, 2011 I'd use 4 ports. If your box volume is 7 cubes after displacement, the ports should be about 14-15in. to tune to 33hz. 2 4in. ports isn't enough. 2005 Subaru Outback Wagon Pioneer 9400BH Fi Q 15, SAZ1500dV3 The first build>>> http://www.stevemead...-outback-build/ 140.9 @ 36hz Sealed on dash!

TheBetterMethod Posted October 7, 2011 Report Posted October 7, 2011 If you use two 6in. ports, the length would need to be about 15 and 5/8in. tuned to 33. 2005 Subaru Outback Wagon Pioneer 9400BH Fi Q 15, SAZ1500dV3 The first build>>> http://www.stevemead...-outback-build/ 140.9 @ 36hz Sealed on dash!

trulywickedcustoms Posted October 7, 2011 Author Report Posted October 7, 2011 Thanks guys we can't do 6" ports bc the size of the flare on an aero and the top of his box is to small, I knew the 2 ports was small on the 15's but he was just playing around with some calculator on the12volt.com or something but that was temporary anyways So I guess wel be doing 4 4" @ 15" long and trim them smaller if desired thanks guys! *2013 NEW BUILD* 12- 18" Crossfire XS v2's B pillar 4th order wall 4- Crossfire 8K mono blocks 40+ pro audio mids tweeters and horns 3- Singer alternator 400a external regulated alts tons of audiotechnix wire 24- XS Power D1400's -TEAM XS POWER- -TEAM CROSSFIRE- -TDH-
TheBetterMethod Posted October 7, 2011 Report Posted October 7, 2011 Yeah man, 4 4s at 15in. should be good. 2005 Subaru Outback Wagon Pioneer 9400BH Fi Q 15, SAZ1500dV3 The first build>>> http://www.stevemead...-outback-build/ 140.9 @ 36hz Sealed on dash!
