Car Stereo Amplifier 4-Channel in Johns Creek, GA

Car manufacturers give their stereos a limited amount of power. Adding an amplifier can dramatically improve the head unit’s output to the speakers and make them sound louder and clearer. Start upgrading your car with a new aftermarket stereo. It will not only enhance your listening experience, but it can also increase the value of your vehicle when you sell it.

Speakers

Whether you want to boost the volume on your favorite tunes or watch videos while you drive, the speakers used in a replacement stereo have an impact on sound quality. Look for a pair with high sensitivity ratings and power-handling capabilities that match the output of your new head unit and amplifiers.

Factory stereos are designed with cost and commonality in mind, aiming to provide the average car owner with a decent audio experience. Aftermarket stereos use better components that offer superior built-in power and improved circuit design for cleaner, richer, more detailed audio.

Some aftermarket stereos come with extra features that make driving easier and more fun. For instance, a stereo that is compatible with phone operating systems like iOS and Android lets you use music apps and hands-free calling while on the road. Some even include GPS navigation that prevents you from getting lost while enjoying your favorite songs. Others have superb displays and changing light schemes that heighten the aesthetics of your vehicle’s interior.

Amplifier

For a great audio experience, stereos need to be paired with an amplifier. Look for one that has multiple channels for a more customizable sound and offers presets to help you adjust the audio settings. The amplifier also needs to be compatible with the vehicle to prevent damage.

Some aftermarket stereos include lighting that flashes to the beat, adding a fun and modern touch to the car interior. Others have high-tech displays with unique layouts that enhance the visual appeal of the device.

If you choose a touchscreen stereo, look for Apple CarPlay and Android Auto integration to bring your smartphone features into the vehicle. This allows you to use phone apps for navigation, music streaming, and hands-free calling while driving. Regardless of what type of stereo you choose, ensure the user interface is intuitive to keep you focused on the road. Look for buttons that are easy to press and have a good hand feel.

Subwoofers

Adding bass to your stereo with a subwoofer is a great way to bring more depth and clarity to your music. However, some factory stereos don’t come equipped with RCA pre-outs (the red and white inputs that rca jacks plug into to produce sound), so you can’t add an aftermarket subwoofer system.

Upgraded stereos can also include more advanced technology than your factory unit. You can find units with Bluetooth connectivity, compatibility for Apple CarPlay or Android Auto, and rearview camera integration. Some models even offer voice control.

You can find a good quality aftermarket stereo for about $100. Look for a single- or double-DIN receiver. You’ll also want to choose a model with a touchscreen. These are the best for connecting to your phone for music streaming and hands-free calling. Some models have GPS navigation, as well, which can help you avoid getting lost while driving. This feature is especially useful for drivers who commute long distances or frequently take new routes.

Display

In the past, upgrading your factory head unit was a common practice in search of greater sound power and quality. But the landscape of aftermarket car stereos is changing, and there are a few things to keep in mind before you make the upgrade.

In particular, removing your factory stereo can disable important features like steering wheel audio controls and integration with OEM telematics systems such as On Star. If you want to hang on to these features, be sure the new stereo can integrate with them by looking for compatibility info or purchasing a wireless adapter.

In addition to a stunning, interactive touchscreen display, the best aftermarket stereos feature built-in essentials like smartphone integration and voice control. Many of these units also fit dash openings that were previously too small for touchscreen receivers.
