Power, sound quality, remote bass control so you can control the power from the front seat.

The $$$$$ if you paid full price cause you got screwed. I don't think it is worth the retail price of $500 but if you can get it for around $300 it is well worth it

This is an all around great amp. The power coming out is great, the sound quality is amazing and with it being a dual mono amp it is very user friendly. The power rating is 500 x 1 @ 4 ohms, 750 x 1 @ 2 ohms, and 1100 x 1 @ 1 ohm. I have this amp hooked up to 2 12" dual voice coil phoenix gold tantrum series. In a competition I hit 137 db with everything up full. When im just going around on the street I have the bass on my deck at -2, the gain at half, the bass boost at half, and the remote bass control at half and it still pounds hard enough to hurt my ears.

For the price You cant go wrong. Im pounding 3 jl 10w0 4ohm wired in parallel down to 1 ohm. The amp does not get hot what so ever. Pounds the hell out of the jl''s. Remote gain knob is nice. The jl''s are in a sealed box with about .80 cubic ft. of air each sub. It''s installed in full size bronco with alot of air space. Ive invested a little over $550.00 total , amp + subs. Kick A$$ bass for the money. Nice tight bass for the metal heads and hits low for the bass heads. Perfect for my first system.
