I have a Cobalt SS 4 door, Running two SA 12s at 1ohm on a 1800.1D audiopipe.
I hooked em up and became curious of how much better they might sound if I faced them forward instead of rear then sealed off the surrounding gap with some great stuff foam. Or leave it rear? I have done a few boxes facing port and sub forward however the output was not too great, however it was not sealed when I made these attempts. Does sealing it off make all the difference? Got some photos to show how small a gap is left from this box in the trunk, below.
