ChrisLun Posted September 10, 2011 Report Posted September 10, 2011 I am really considering doing a 4th order wall build in my car. My question is, will this idea work with 8 of the SA-12's.... 0.7^3 sealed and 13.5^3 ported with roughly 220-230 sq inches of port area. And also what type of power should be ran. Never build or played with a 4thso I am a boob to these. This will be for a daily ground pounder. So if this will not work for daily please say so also.

ChrisLun Posted September 10, 2011 Author Report Posted September 10, 2011 I have never built a 4th so if there is any changes that could/ would be done please express em.... I wonder a clamshell would work better? Quote 2006 Dodge Charger (2) Kinetic 3800 (1) DC Power 270XP (4) T1-12D4 (1) T2500BDCP (2) T400.4 7.5 cubic ft.

Ray Posted September 11, 2011 Report Posted September 11, 2011 .7 is about right. I like .85 And ported section just keep it at 1-2.3 ratio Choke the port to 12-13sqin per cuft Your on the right track man Quote 2008 California state record holder 157.2 Bassrace2009 California state record holder 157.0 BassraceRollin 50's 158.7db2009 King of Cali Bassrace2009 USACi score 160.5 @ 42hz
Ray Posted September 11, 2011 Report Posted September 11, 2011 Tune the ported side to 38-39 Should play down to 26-27 up to 55 ish Quote 2008 California state record holder 157.2 Bassrace2009 California state record holder 157.0 BassraceRollin 50's 158.7db2009 King of Cali Bassrace2009 USACi score 160.5 @ 42hz
Team Nemesis-DJ Posted September 12, 2011 Report Posted September 12, 2011 .6-.8 is just fine for 4th order sealed per sub Quote
