Hello, I need help design/constructing an enclosure for a pair of American Bass XD 8's that is being shipped to me. I'm looking for a chest pounding lows. 1-2.5 cuft gross is what I'm looking for, if I need more I can deal with it being more. I'd like to run both subs, but am fine with running one. The amp that I'll be running is an AudioPipe 1500 apsm, I'll be looking for another amp after I sell my 2 12" skar ivx.
