What would be a reasonable time i would be able to play a 1100 watt amp off a car batter thats turned off with out going dead. I know you can not give exact but with no alt upgrade and just a norma batter if you need to kno the battery i can check tomorrow it is nothing speical tho. How long can you run you system with out your battery going dead. i was thinking 15 - 30 min. whats your numbers
