Also, if the amp is bridged down to one channel, the amp will "see" it as a 2 ohm load. In that case, you need to series wire the voice coils on the sub, other wise the amp will act like it is a 1 ohm load and either shut itself down (if it has overload protection), blow fuses, or just kill itself trying to feed the sub. You could, however, do 2 identical subs, and wire them up in parallel, giving you 2 ohm loads on each channel, which the amp will handle fine. It is not advisable to wire one voice coil to one channel and the other voice coil to the other channel, due to stereo separation, which could cause one voice coil to sit idle while the other is pushing the sub, or the voice coils may try to move in opposite directions, which will cause them to overheat and burn, because the sub isn't moving. I hope this makes sense, since it has been a while since I have renewed my MECP certification.
