bdks Posted April 11, 2009 Report Share Posted April 11, 2009 I am about to install 2 18's in the back of a Gmc Sierra Ext. Cab. I will be taking the back seat out. My question is should I have the subs and port facing up or Subs facing forward and port up. I was told to have the subs facing forward and port up but I would like more opinions on this.
