BOX DIMENSION HELP...  Hey how are you... I’ve been looking at your feeds off and on for a day or two and entered as a member today.  You definitely seem to be the go to person. I own a 2009 Dodge Charger I’m using an Orion 1500.d1z amp ... I’m powering two sundown SA-12D4  subs that I’m running mono at 1/2 Ohm

one of the replies you responded to was to the exact subs I’m using 

however my box height max is 14” max width is 30” and at that height and width my box total length is probably right short of 30” more like 28” I haven’t sized  the opening for more then 28” in length in order to have it slide in easily. Lol The dimension to get me to approx 32hz . And would it be better to do two separate chambers on a box that is side vented or an open box for the two subs with one vent are there advantages to a single or double chambered box I’ve briefly tried a couple free app software (which don’t all seem to be equal but free I guess is the clincher)  I’m getting slightly different answers could you please help with some accurate dimensions with a non flared side port ? thanks so much 

Your time and response is greatly appreciated perry smith
