At Horizon Audio, we carry both vehicle battery replacements as well as dedicated audio batteries. High-performance car audio systems sometimes require more power, and the original electrical system in some cases just isn't up to the task. If you want more power when the engine is off, then the best option is to install a second battery. Check out the vendor links below, call, or stop in to one of our stores to find what battery solution is best suited for your needs.
