In a store how do they power the display models of car headunits, amps, speakers, and subs?

Do they use car batteries, PC Power supplies, or what do they use to power all of the car audio stuff in the store on display?

Power supplies. Batteries are a mess to maintain in doors. Power supplies are cheaper and require little or no maintenance.
