106 sound system battery power

I have 4 watts, including 1500 watts jbl amplifier, 1400 watts pioneer woofer and two original speakers in the front and 2 490 watts in the rear pandizots. How long can the vehicle work when it is not running? After a long period of time, will there be a problem, will it damage the battery? What if you fill my speaker slots in the back doors empty in them, what would you suggest?

Do not look at what they write so high watts, shaved writers to some of the columns.
