Oh, I'd guess maybe 10-12 hours ....... if you're just sitting in your car listening to music longer than that ....... unless you're on a stake-out, you may wish to re-evaluate your lifestyle .....

You have to take some variables into account as excessive cold and excessive heat shorten battery life, what kind of head unit (old head unit should use less power than the new head unit), do you an aftermarket amplifier, and etc.

I left mine parked for 5 weeks while i was overseas on holiday.
The battery was fine and the car started on first crank of the starter motor.
So my guesstimate is it can last longer than 5 weeks.
The radio will automatically switch off after one hour , this is annoying at drive in movies because the start button has to be pressed every hour to keep the FM movie sound on.
So the radio can be used for at least 3 hours and the battery still starts the car okay.

Just have a pump handy, jam it up a few PSI if you notice the interior lights beginning to fade.

In all seriousness, there are many variables involved here. Volume? After market speakers/subwoofer involved? Ambient temperature? Type of music?
