My setup is as follows:
2007 OEM battery
My battery has not exhibited any signs of weakness and the last time I took it to the dealer for an oil change, they checked the battery and it was good.
My question is this; my new HU can play DVD's and I was wondering approximately how long I can watch a DVD with the car NOT running? I know this is a subjective question, but I was just wondering from a hypothetical point of view based on the power required to run the system.
I'm definitely not an electronics expert, but would adding a capacitor to my system give me additional time?
