Probably a good time to check the voltage on the car battery it should be circa 12.6V if it’s below 12.4V use a trickle charger to give it a boost. The battery may need changing as it’s six years old if it drops below 12V

Either battery getting old or you’ve just been running too much equipment with the engine off. Having the headunit on, using the radio or playing music will drain the battery quite quickly if the engine isn’t running.
