[QUOTE="Zedfour, post: 8671936, member: 676806"] Hi I’m New to the forum and I’m desperately trying to build an enclosure for 2 x powerbass xl-840d 8” subs. The problem is, I have a 2008 Z4 roadster... I’ve custom fabricated the dash and installed a pioneer avh-8500bt double din, I made tweeter pods for the A pillars and have 3 way hertz energy/ audison prima mixed components front stage run off a Helix B4 blue 4 channel & alpine 6 x 9s custom built in the rear cubby holes run off the hu. ive removed the rear shelf so the trunk isn’t sealed! the subs are 200 rms each and I have a massive audio b2 nanobit to run them @1ohm is there anyone who can help me with what size enclosure I need? The max size I have is 32” width 12” high and 14” depth would they be better firing up, port back? This is the sub spec [ATTACH]4810._xfImport[/ATTACH] [/QUOTE]
