Hi guys, i've been trying to research this topic all night...What kind of sub/port configuration works best for a 2007 mercury grand marquis? I've done sub back/port back and it works well but i was wondering if a different combination will work better or worse. (ie, subs up, port back, or subs up, port up). Any help will be greatly appreciated. Im not looking for opinions. I want to know what combos others are running and results of each type.
