chronic2001 Posted July 21, 2013 Report Share Posted July 21, 2013 I have a 2013 accord coupe and wanted to do a 4th order with my 2 8's. I wanted to try out the new x12 but don't think I have enough room in the trunk. So I found a post when I searched that suggested .5 sealed and 1 ported with like 50hz tune. Has anyone played around with 4th orders and the sa8v2s? Any help would be appreciated. I will be running saz1200 at 1ohm. Goal is best sounding and response I can get.

DylanBunch Posted July 21, 2013 Report Share Posted July 21, 2013 I don't have experience with those subs but a rule of thumb for 4th orders seems to be, the lower the ported to sealed ratio (1:1) the better bandwidth but less output, higher the ratio (3:1 3 ported, sealed 1) the more output but less bandwidth. A lot of people do 2:1 and port wise, id go somewhere like 45-50hz with 16-18" of port per foot. Im no expert so someone who is could chime in and be more detailed but I almost did a 4th order once and that's what I was told by people on here Quote 2006 Ford Explorer 2 Team AA/Sundown 15s 6th order Ct Sounds 7k 4 PRV Mr500 8s Rockford p1000-2 Team Subsonic Lows Link to comment Share on other sites More sharing options...
chronic2001 Posted July 22, 2013 Author Report Share Posted July 22, 2013 Ya I'm looking for the post I found from Jacob. I think those were the specs he was running on the one they built. Thanks for the advice, I'll post the info if I can find it.
