Ok, while over spring break I'm going to try out my Epicenter and my USA-300 in my S-10 for shits and giggles with a DD 1008 I have laying around. It is going to be a downward firing box, 1cube @ 40hz. My only question is what way to fire the port? I've been told to the side by some people and up by others... Anyone in here done a downard firing ported box in an Ext Cab S-10?
