I've searched and some people say it dont matter but I just want other opinions. I am building my box for my two 18" BL's in the wall in the explorer which is going behind the 2nd row seats. I am worried if the port is along the bottom that the seats will block the air, and I'm really shootin to do a hair trick. I asked one guy on youtube and he said "i can guarantee you port bottom will give you better low end and overall louder. for spl and daily" Just looking for opinions. And box pictures will be up sometime soon in my build thread.
