How to power custom accessories when battery connection isn't an option
Hey gang - this might seem like a dumb question, but here it goes: I am bringing my car to a show at a convention center. I have two batteries in the car that power everything, but Fire Marshall code requires me to disconnect everything from all battery terminals.
This will unfortunately prevent me from using the car's custom accessories, lights, sounds system, etc. In total about 800 - 1000 watts.
I do have the option of asking them for an AC power outlet, but my question: how can I setup these accessories (currently connected directly to the batteries; not to an interior 12v power outlet) to run off AC power?
Basically, is there anything I can get that would allow me to power the amps and accessories even though they will not be connected to the car's batteries?
THANKS IN ADVANCE!

I believe certain battery chargers (which plug into the wall) can be hooked up to the battery cables and in the absence of a battery would run the electronics. Do research/tests before trying this at the show.

That's exactly what you want, an inverter. Though finding one that can power that much wattage may be pricey. Every computer and phone and tablet and audio receiver uses an inverter. Battery chargers can work but will over heat since their duty cycle is far too small. They would overheat if left above 10 amps for a longer duration. Sure you can buy 50 and 100 amp chargers but they are meant as an assist to start a low battery or give a short charge. Don't believe me, hook up the 50 amp side to a battery and give it 5-10 mins. Hot.

There is a wide variety of inverters or 110vac to 12vdc converters, commonly found on the motor home aisle at WalMart and local autoparts stores, tractor supply and so on.

Personally, unless it's an audio competition or category I wouldn't even hook up the stereo, just the lights or visual stuff. I've reached the age where people blasting music at car shows I don't like is racquet and loud music when I'm trying to talk to a guy is disrespectful to patrons-- that is unless it's an audio competition.

Wrong term. An "inverter" is DC-to-AC, or driving an AC appliance from your car's DC system. Thinking going camping and taking your home coffee maker.
What you want is a AC-to-DC "CONverter", or "power supply". Makes a BIG difference in your Google searches!

Lots of amps and expensive!
