How to Choose a Car Amplifier?

Choosing a car amplifier can be challenging, especially for those unfamiliar with the technical aspects of car audio systems. However, considering a few key factors can help you make an informed decision.

Number of channels

The first thing to consider when choosing a car amplifier is the number of channels needed for your speakers and subwoofer. A channel refers to a separate audio signal that can be amplified independently.

Amplifier class

There are four main classes of amplifiers: Class A, Class B, Class AB, and Class D. Class A and B amplifiers are not commonly used in car audio systems, as they are less efficient and produce more heat. Class AB and Class D amplifiers are the most popular choices for car audio systems.

Power output

Power output is measured in watts and is essential when selecting an amplifier. You should choose an amplifier with a power output that matches your speakers’ power handling capabilities. For example, if your speakers can handle 100 watts of RMS, select an amplifier that can output at least 100 watts of RMS per channel.

Size and form factor

The size and form factor of the amplifier are also essential considerations. You should select an amplifier that fits in your car and is easy to install. Some amplifiers come with a compact design that can fit under the car’s seat, while others require more space.


When upgrading your car’s sound system, a high-quality amplifier can make all the difference. This article has compiled a list of the best car amplifiers to help you find the perfect one for your needs.

No matter which car amplifier you choose, consider your specific needs and the specifications of your car’s sound system!

Frequently Asked Questions – FAQs

Can I install a car amplifier myself?

Yes, it is possible to install a car amplifier yourself. However, it is important to note that installing a car amplifier can be a complex process and may require some technical knowledge. If you are not confident in your ability to install the amplifier yourself, it may be best to seek the help of a professional.

Can a car amplifier damage my car’s electrical system?

Yes! A car amplifier can damage a car’s electrical system if not installed or used properly. For example, if the amplifier is not grounded correctly, it can cause electrical interference and damage to other components in the car. Additionally, if the amplifier is not compatible with the car’s electrical system, it can cause damage to the battery or alternator.
