A car amplifier that overheats is a dangerous fire hazard. If it catches on fire, it will be damaged and will most likely damage your vehicle. Preventing your car amplifier from overheating is fairly simple, but the peace of mind you have knowing that your vehicle and anyone in it are safe is well worth your efforts.
Ensure that the car amplifier has the appropriate fuse to prevent power from reaching it in the event of a short or other mechanical problem. The fuse rating varies with every amplifier. You can usually find this information on the information sticker under the amplifier.
Give the amplifier space. The number one reason why an amplifier will overheat is lack of space around it. When you install the amplifier, it should be placed on a solid surface, such as a piece of wood. Additionally, you should try to leave at least one inch on every side of it empty.
Turn it off periodically if you are on a long trip. A good rule of thumb is to turn it off when you stop for gas the first time and then turn it back on when you stop for gas again. Do this until you reach your destination.
Get a convection or forced-air cooling system. Many amplifiers have an internal convection cooling system. As such, an external convection cooling system or venting system is usually an appropriate option.
Tips & Warnings
- After installing or modifying sound system components, you should feel the amplifier after ten full minutes of use. If it is hot, you will need to modify the cooling system.
- Never continue to use a car amplifier that you know is overheating.
