Alright, I'm getting new gear. This will be going in a single cab '04 dodge ram 1500. Previously I had the box in between the driver/passenger seat since I took out the middle seat. The box was around 5 cubes and I had some more to work with (plus behind the seats to work with). Anywyas, I'm wanting a pair of 12's or a single 15'', maybe a single 18" if it will fit. I want to throw like 3000 at the 15" and 1500 per 12". My budget is around $300+. Recommendations?
