I've decided to build a 4th order bandpass for my MA Audio HK12X2 sub. Problem is I'm not exactly sure what specs I need to build it to. I'll be porting this through from the bed of my single cab 06 GMC. Basically I'm needing to know what internal volume each of the 2 chambers need to be and also get an idea on what correct porting would be. Any gurus out there got any insight for me?
