It is very important to match the subwoofer to your amplifier.

If you are using a MONO amplifier, most new designs will give you the most amount of power they are capable of producing at 2 ohms... If you have one of these amps then you want a 2 ohm subwoofer.

If you have let's say a 2 Channel amplifier and you will be bridging it to a single channel amp and in the specs it says something like
75Wx2 at 4 ohms per channel
100Wx2 at 2 ohms per channel
200 Watts X 1 at 4 ohms bridged... Then you want a 4 ohm sub.

If you run a 2 ohm sub on an amp that is designed to be at 4 ohm, you will overheat the amp and in most cases amp will hit protect mode and shut down...

If you use a 4 ohm sub on a MONO amp designed for 2 OHM for the most amount of power, you will only use that amp at about half the power it can otherwise produce.
For example rating will be "250 Watts @ 4 ohms" or "350 Watts @ 2 ohm" in this case you want a 2 ohm sub.
