Basically what it says. Silverado 1500 ext cab. I took out the back seat and made a platform for the enclosure to sit on. Its a 10^3ft net box, for 2 18'' mach audio mj 18m's.
I want to go with subs up, and port up. (port all the way to the passenger side of the box) (id prefer middle but wouldn't work im sure)
any suggestions or would this just cancel out? should i go subs forward, port up?
