A car stereo amplifier produces more heat than you may realize. If not kept under control this heat can not only damage your amplifier but could actually create enough heat to start a fire in your car.
Step 1 – Check Your Fuse Size
Locate the fuse specifications you will find on a label stuck to your amplifier. Be sure the fuse in your amplifier matches these specs. If it doesn't, replace it with the right fuse.
Step 2 – Install a Cooler Fan
Typically your amplifier can be kept from overheating by a flow of air past it. If your amplifier is not located in an area of your car where air circulates freely, install a small electrical fan connected by electrical wires to your amplifier's power wires.
Step 3 – Make Space around Your Amplifier
Even with the help of a fan your amplifier can easily overheat without proper air circulation. Make space around your amplifier by removing articles that may be placed on it or near it.
Step 4 – Manually Check Your Amplifier's Heat
When installing your car's amplifier, place it where you will be able to check your amplifier's heat. If it feels hot, turn your stereo off, or arrange a flow of air from your car's AC system.
