An amplifier with a 12V output needs a 14V or more power supply. Do you have this power supply for the amplifier?

If you need to control the speed of the motor then PWM can be used or a linear audio amplifier IC can drive 500mA into a motor when the motor is running but it might not be able to supply the 5A to start the motor running.

You might be able to get what you want out of one
of the TI/Unitrode PWMs. Certainly so if you used
power MOSFETs, but possible even bare. You don't
really want to be linear and dissipating 3-5W in the
amplifier.

A class B amplifier, build from a v=+2.4 non-inverting OP amplifier with a complementary emitter follower as output stage should do
