Sounds like a motorhome stereo. :)

It would be far more energy efficient to sell the home stereo and install
a car stereo. The energy loss (expressed in heat) from an inverter big
enough to provide the 500W AC (@120V) necessary to drive your stereo and
power amp are hideous, compared to a simple 12V regulated power amp made
for cars.

If you ever want to run the stereo with the engine off, you'll eat your
battery rather quickly.

Again, AC elements that are made for high wattage and heat are not suited
to automotive applications without a regular generator or a LOT of juice
in the form of heavy batteries.

There are many forms of battery isolators made for this purpose.

Well, of the inverters that I have used, none of them puts out enough
wattage efficiently to justify them over a good quiet Honda generator.

Admittedly you can't use the generator when you're cruising down the
road, but I suggest that you won't want to be using the rice cooker or
a hair dryer at that time either.
