Most car amps have an auto shut-down and do not have a cooling system and this can be irritating for most car amp owners. If you want uninterrupted high quality sound, you should get a car amp that is not just durable but also protective against thermal problems and does not heat up a lot even with long hours of use.
What is the overall price? Car amps range from $50 to $200 and above but this all depends on its features. Make sure what you get is what you pay for so that you will have the best for your money.

What do the reviews say about the car amplifier? Get to know if there are cons that can be bothersome on the car amplifier. There should be a few cons but they should not be deal breakers. Weigh in all the pros and cons of the car amp before buying and using it.
Is it a class A/B or a class D? Take note that there are differences when it comes to power outputs of a class A/B car amplifier and a class D car amplifier. Class D amps are mostly pricier than class A/B but it all depends on its features.
What is the maximum power output? This also depends on whether you get a class A/B or a class D and the size of the car amplifier.
Can it protect the unit against dangers such as short circuit, overloading and thermal problems? Car amps are frequently used and they can heat up fast if they do not have a good thermal protection system. They can also be in danger of short circuits and overloading and this is why you should have a car amplifier that protects from all of those things.
Despite its weight and features, is it very portable? Most car owners are looking forward to a car amp that is portable and easy to install on almost any car or vehicle to enhance their subs or speaker system.
