Open-Box Car Amplifiers

Most audio systems—including professional audio, home audio and car audio—rely on some form of amplification. An audio amplifier boosts the electrical signal coming from your audio receiver and increases the power sent to the speakers, which improves the overall power and quality of your sound.

Your car stereo receiver coordinates the audio inputs in your car’s sound system, like radio signals and Bluetooth connections, and most factory-installed systems include a small amplifier. However, if you are looking into tips for upgrading your car audio, a dedicated car amp provides loud and pristine audio.

Choosing the best car amp starts with deciding how many speakers you want to amplify. Amps are categorized by the number of channels they power. A mono subwoofer amplifier powers a single speaker while a 2-channel amp powers two speakers, and so on. Powering a sound system with four speakers and one subwoofer requires a 5-channel amp. If this is all new information to you, it would be wise to consult with Best Buy’s car electronic installation team to figure out what is best for your car.

Subwoofers are designed to produce low bass frequencies, and they require significantly more power than most factory in-dash receivers can provide. Therefore, an additional car amplifier is required when installing a subwoofer in your car speaker system. For simplicity, you can choose a powered subwoofer with an integrated amplifier. But, if you want to increase power to more speakers than just the subwoofer, you should invest in an amplifier that connects to your overall car stereo system.

If you feel up to installing your new amplifier and subwoofer on your own, review Best Buy’s collection of car electronic installation parts and accessories to find what you will need. Alternatively, you can use Best Buy’s car audio installation services to cover the job for you.

When you make the decision to upgrade your car audio, you will be improving your car’s entire entertainment system. A car amplifier can take your sound system from mediocre to astounding, providing booming bass, sparkling high notes and clarity at any volume. Amplification also brings you the power you need if you are adding more speakers or larger speakers to your car.
