View Full Version : super box 2 :-)

10-21-2007, 03:11 PM
As I was informed I posted in the wrong forum for "hypothetical box construction", so here I am. I have an spg-555 going into a 07 frontier. Have general box dimensions and location figured out. I was wondering how downfiring was vs anything else. The box will also be ported so any help will be great. Thanks
