If a 2 ohm sub is the same price as a 4 ohm sub and its the same model, why would anyone want a 4 ohm sub when it is cheaper to get more power with 2 ohm?
I don't understand..
2x the power with 2 ohms instead of 4 ohm

what everybody else has said. and amps do not always run twice as much power at 2 than 4 either.

every amp is different. Some 2 chan amps are only 4 ohm mono stable, while some a 1 ohm stable. Some amps like JL are stable from 1.5-4 ohms. Some are regulated power supply's and some are unregulated. Some amps double in power from 4 ohms to 2 ohms some put out the same power. Every amp is different. Dual 4 ohm subs and dual 2 ohm subs allow for multiple wiring configurations to fit a specific amp.

Ok it bepends on the amp. A 4 ohm sub is better for sound and a little kick. You can also use a 4 ohm sub for a house speaker. But a 2 ohm speaker you can brige off your amp. 2 ohm is used for more kick.
