I'm going for sound quality and here is what I have to work with. Eclipse CD3100 H/U. Install is going to be in a mid size extended cab truck. The box size i've come up with is going to give me 0.68 cubic feet without speaker displacement. So I know its going to be an 8 or 10 inch sub. The amp is hopefully going to be a Zapco Reference 350.2 (350X1 @ 4 ohms). My budget is $300 max.
So with that said what is my best choice? Also, for any truck people what is the best way to have the sub face for SQ? Thanks for any help.
