How long have you played your radio with the engine off?

or do you just keep engine on and play away?

 

I have a 400 watt pioneer amp running the speakers in my truck. No sub or anything like that and I can play for about 2 hours. After 2 hours the amp automatically kicks itself out once the voltage has dropped too much. I then can still easily crank the truck but I can tell the battery is down some. I am 1st gen though.

 

I have played mine loud with 1340 watts for over an hour, probably could do it longer tho. But I have a 96 tacoma.

 

About 15 minutes before the radio shuts off.

 

I have had mine blaring for a good hour and half before..
i have two kickers up front, and a 8 inch sub with a pioneer amp

 

Stock with Pioneer head unit, had it running for at least 2.5hrs painting the sliders in the rain (in a shed). Didn't have it very loud though.

 

Thanks for the responses guys.
