Well for an amp that is 4 ohm bridged only and 2 ohm sterio your really stuck with either wiring the sub down to 2 ohms or running each voice coil to each side of the amp. but your sub will wire at 2 ohm or 8 ohms or 4 ohms x2 so .... thats about the best you will be able to do. you would get the best out of all that if you had a monoblock amp. something thats 1 ohm stable. but 500 rms or so is about the best your going to get to that sub. I suggest a smaller box. something thats maybe 2 cubes at about 38 htz. thats going to give you the loudest bump and still perform and sound well in all styles of music.
