I am going to get a Hifonics mono amp and wire the sub(dual 4 ohm) to 2 ohms for the amp. Probly get a bx1000d that puts out about 500 watts rms @ 2 ohm which is what the sub is rated for. Also I listen to hard rock/metal and sometimes a little rap music. I want a small sealed box so I don't lose too much cargo space in the back.
