Your battery has apparently discharged for some reason. It's possible that your battery is bad...OR you left something on in your car....OR your amplifier (or some other device) is draining the battery when the car is off.
- Charge your battery.
- Have the battery load tested to verify it's OK.
- If you think it's related to your amplifier, pull the fuse (or power lead) going to the amplifier and let the car sit overnight.
- If your car fails to start again after sitting for a long period of time (because the battery is dead again), you may have to do a parasitic draw test to check for abnormal electrical drains on the car while it is not running.
