The best car audio battery on the market is the XS high-performance battery, thanks to its incredible power. This power cell has 1,000 cold-cranking amps and a max output of 3,300 amps. It also requires no maintenance, is still proof, and is vibration resistant.

Unless you want to listen to music with your engine off, adding a dedicated car audio battery isn’t going to do you any good—and it may actually hurt. That might seem counterintuitive, but the reasoning is simple. The battery in your car is there to serve one purpose: to provide enough amperage to start the engine.
