Has anyone designed a car amplifier that runs from the high voltage system of a hybrid car? I'm thinking designing the power supply for it would be almost exactly like designing a power supply for a home amp. In fact, many engineers have run unmodified universal input power supplies from the high voltage system of a Prius, meaning an off-the-shelf power supply can be used!
The obvious benefits would be greater power available (great for those building loud car stereos!) as well as higher efficiency due to lower currents needed. The obvious downside is that more care would be needed when connecting the amp, but it really isn't any different from wiring home AC power.

It's 200v for a Prius, or right between the peak voltage of 120v AC and 240v AC. Thus, a universal input power supply can be used.calvinhpk said:what's the voltage does the hybrid car runs on? 24V? 48V?
Some have run several kW of loads from a Prius:every car has its own setup, seen 100v+ cars too. there you would need only full bridge D amp[output stage] and you would have several kw
But I wouldn't do that, batterys are not that good to have so many large consumers to power

And universal input power supplies will run from the electrical system of a Prius:

dont think its a wise idea to tap off the main battery pack. bass transients might actually trick the car into thinking the batteries are lower than they actually are and cause the engine to sit there and start/stop trying to recharge.
id go with a class D amp or tripath based amp that has little draw and connect to the small 12v battery.

POWER YOUR POWER AMP IN A HRBRID CAR
My Electric Car is equipped with a DC to DC Converter that has an input range of 120 – 350 VDC (http://www.powerconversion.com/assets/mp_1227738018.pdf), the output is over 40 A at 14 V.
