you need to find out the rms on the sub and the amp to match it up. if it is a dvc with 800 watts rms than you will need a amp with atleast 800 watts rms power to push the sub.
with a mono amp connect both of the positive terminals with a wire. then take another wire from the positive and connect it to the positive terminal of the amp. do the same for the negative side.

with a 2 ch. amp connect two separate wires in each terminal of the amp, total of 4 wires 2 + and 2 -. take the 2 + wires and connect 1 of each to a + terminal on the subwoofer. do the same for the negative.
