How long would battery last?
Always wondered...
Assuming that the car is off, roughly how long would a lcd screen deck last while playing a movie at normal volume?
Would it be even possible to make it through a ~2hr movie?

Yea easy depending on how big your car stereo is. If you have amps and shit it might not make it but if its just stock components then it should make it.

Berz out.

will depend on the battery too. the batts i use have enough reserve that theyll still start your car after drawing over 11 amps of current for 8 hours straight. And thats just using one batt. Batts wired in parallel = double capacity
