Phoenix gold XS2300, one of the best mid ranged amps ever built. Class A amp, 2 channel 300w. You can find all specifications on the phoenix gold website, this is a xs gold. I've ran this on a few different boxes, and it really hits hard, very clear, and is all around a awesome sub amp. Has subsonic filter, etc.. The box is decent, nothing real great, has a single 10" MTX Blue Thunder wooder.Not sure on the specifications. I want to say 800w max, but I cant get into the box anymore as its basically glued together. 120 for both local pickup Or 85 plus shipping for the amp
