Your amp has a 12v (hot) wire that is switched and a ground wire or chassis ground.
Connect your fan the same way: 12v (hot) switched, chassis ground. Then they will come on and off together.
If your amp is overheating it may be that your speaker load is too low impedance for the amp design causing over current and shutdown. Disconnect the speaker wires from the back of the amp and test each speaker wire with an ohm meter. If any are below the minimum ohms rating for the amp you have a problem. Most modern amps can run 4 ohms all day. Many amps can run as low as 2 ohms.
