Red- Power, Black- Ground, Gray and the Green- + and - speaker connections. The vehicle it came from probably had just one speaker.

Red-power, Black-ground. The other two wires are right and left speaker +, the speaker grounds are both run to the common ground for the radio. I haven’t seen one of those in 35 years. Lol
