I’m looking for a ballpark figure, nothing exact. I’m wondering approximately how long I can have my car stereo on with my engine off without draining the battery down too far.

I have an aftermarket CD player which is 17 watts RMS per channel (45 maximum). I don’t have any amplifiers or subwoofers hooked up.
