The basic process involves running an audio signal to the amplifier, running an output from the amplifier to the speakers, and finally running power to the amplifier. The process can be very complicated though so you should purchase a book or research the process online.

Most Amplifiers require a ground and then a 12v power line, usually almost direct to the battery. Then there will be a lower voltage remote lead from the radio, which swtiches the power on and off. There will be inputs, either RCA Preamp in or Speaker level in and there will be speaker lines out to the speakers.
