Does it come w/remote on/off switch? Can it be grded with 4 guage wire? Can it be mounted in a vehicle upside down? Will 2 deep cycle bats run this?

The PW6000-12 includes a wireless remote and receiver base. It can be grounded to the chassis using the ground screw with 4 AWG cable. The unit should not be mounted upside down. 1 battery is all that is required to power the unit, but more batteries will give you a longer run time especially at higher wattages. Some people have this unit connected to banks of batteries 20 deep.
