I have a dual voice coil 12 in infinity subwoofer, Now i listen to all sorts of music and i like to hear the pound of the bass not the loudness i have a 4 channel amp thats 1200 watt running my rear speakers and the 2 channels are left to be bridged to the amp what enclosure is best sealed, ported, etc
