Frequently Asked Questions (FAQs)

1. How long do car audio batteries last?

If your car is newer, the battery will probably last for four to six hours with the radio on.

Adding a subwoofer, for example, can reduce the battery life to one to two hours.

2. Can an AGM battery be used for car audio?
