The Best Car Audio Battery 2021

Car Audio Battery

High performance car audio systems will require additional power that most OEM batteries will not be able to provide. Installing a second car audio battery will allow you to power the system without relying on the alternator or having the engine running.

The best car audio battery is the XS Power D3400 XS Series, which is rated at 1,000 CCA with a 65 Ah rating for optimum performance for your audio system.

You can have the best car battery in the world but if there is too much current draw from the audio system, you may run into trouble. Installing a high output alternator may be the solution but the engine must be running in order to power the audio.

Car Audio Battery Buying Guide

Running high performance car audio will require further power that a single OEM battery will not be able to deliver. Many people install a higher output alternator but this would only work when the engine is running. This may not be the solution for many as some audio enthusiasts may want to run their high performance audio systems whilst the engine is off.

You could install a deep cycle RV battery that is designed to withstand multiple car audio device drawing power without the need of a power supply from a running engine. However, there are many brands that have dedicated car audio batteries for this exact purpose. To help you make an informed buying decision regarding car audio batteries, we have produced the below buying guide.

Battery For Car Audio System

Why Are Car Audio Batteries Required?

Many enthusiasts will improve their audio by adding additional components such as car subwoofers, amplifiers and so much more. However, with all these additions comes extra electrical loads, which are far higher than average.

To help power the additional electrical requirements, most people will install a second car audio battery as shown in the pictures above. This will allow you to not only preserve the main battery for starting the vehicle but also allow you to run the high performance system without the engine running.

If you have been suffering from dimming of lights or other electrical issues, you could install a higher output alternator. However, this may be far more expensive and still would not allow you to use the audio whilst not having the engine running.

Dedicated Audio Battery or Dual Purpose

There are many batteries that are able to be used as both a starting battery and audio battery. An example of this is the Optima YellowTop mentioned above, which comes with plenty of power but it all depends on the size of your audio system. You can install hundreds of speakers for cars but the power draw will increase with each one, which will cause a range of electrical issues.

If you are noticing lights flickering or dimming, we would highly recommend investing into a car audio battery. A dedicated battery will further increase the performance of your audio system and is a great investment.


Installing a car audio battery will provide additional power to help with the additional electrical loads. Not only do they help with additional speakers for your car but they will also help with electrical load with headrest DVD players and other electronics.

All of our recommendations cover a wide range of different power outputs and budgets, which will help with the additional electrical draw.
