I was sick of not having a sub anymore and I found a local place that still had a couple of them left so I picked one up. Box is a little big, but it sounds great.

whats differencein dual 2 ohm and dual 4 ohm? I dunno what to get im running 1 amp and 2 components and a sub.

The impedance. Most 4 channel amps are not stable @ 2 ohms mono. Get the dual 2 ohm driver unless yours is.
