almost any amp will drive a 2 ohm speaker. You've got to be a bit more specific with your question.
What power do you need? Is the speaker min 2 ohm or is this the average value?
i need amp to drive 4 ohm subwoofer in my car.
i will build the +- 30 to 40V car power supply.
i thinking of build 2 amplifiers and use bridge adapter.
bouth amps together must have around 300 to 500w.
