powering/charging for a show car...

[webshot]

I'm installing a system on a show car that is strictly a trailer queen. I planned on running mutiple batteries but the engine is only started to pull the car on and off the trailer. The system is about 3000 watts plus fancy lighting and video equipment.

What kind of battery and charging setup would you guys use on something like this? I do have a separate AC to DC charger available but it only puts out about 150 amps.

My intial idea was a separate power setup with two batteries strictly for the stereo equipment?

Thank you,

Get a 12v DC generator at a camping/motorhome dealer, plenty of power.

Is it possible to run two batteries in the trunk off the same isolator, say the 200amp Stinger model isolator? Or would I need more than one isolator.

Also do I need to run all the same batteries with this three battery setup?

Thank you,
