The number of amps needed to power two 12-inch speakers depends on their power handling capacity and impedance. Typically, a standard 12-inch speaker might handle around 150-300 watts RMS. To determine the appropriate amplifier, you can use the formula: Amps = Watts / Voltage. Assuming a 4-ohm speaker and a standard car audio voltage of 12 volts, you would need around 12.5 to 25 amps for optimal performance, but always check the specific requirements for your speakers and amp.
