Best Car Audio Battery Buying Guide
As you can see, there are many different varieties of batteries available for use with a car audio system. If you are planning on upgrading or have already upgraded your car’s stereo, you should certainly not forget about the battery.
If you have already upgraded your stereo but haven’t done a battery upgrade, you may have noticed your headlights dimming. This is due to the extra power required for the stereo putting extra strain on your power supply.
Upgrade to premium
There are two main options when upgrading the battery for your audio system. The first is simply replacing your car’s current battery with a more powerful premium battery. While this method can be effective, it is less desirable.
It will still provide better performance and put less stress on other components of your car, like the alternator. If this is the direction you need to go, I would recommend either the Odyssey or the XR Power battery due to their high crank power.
The second and most effective option is installing a secondary battery as a dedicated power source for your stereo. Especially if you intend on installing some big subwoofers and powerful amplifiers in your audio system.
Dual battery isolator
If this is the way you would like to go, then you should consider a dual battery isolator. This will extend both batteries’ lives, plus allow for efficient charging by the car’s alternator. Any of these batteries will be up to the task with this arrangement.
