How do I go about hooking up the speakers to the radio in my 1991 Jeep Cherokee?

I recently bought a 1991 Jeep Cherokee Laredo. It has a newer radio put in but was never hooked up to the speakers. I want to know if anyone knows how I would go about hooking up the speakers and the radio properly so I can have some music. It gets boring driving with no sound but the motor running!
