Custom Autosound Voltage Booster

Will operate 12 volt negative ground accessories from 6 or 8 volt negative ground electrical systems. The maximum output power is a function of input voltage. When used in a 6 volt system, it can continuously supply more than 3-1/2 amps with the engine off, and about 5 amps with the engine running at a fast idle. Because of its very efficient design, its current draw is negligible when no load is applied (10 milliamps).
NOT RECOMMENDED FOR: Power actuated door locks, trunk release solenoids, air conditioner clutches, fans, blowers, power windows, or other electromechanical devices.
