Car battery converters (so called "inverters") are a little problematic. Most inverters don't work well with our highly-efficient Switch Mode Power Supplies and need to be 2 to 3 times oversized. That draws really big amounts of current from the car battery and the wiring from the battery to the inverter needs to be able to handle that. This is by no means a trivial job, so we recommend against it.
Hope that helps
Hey Hilmar, I take it modified sine wave inverters don't make the cut, but pure sine waves work as advertised. Tripp Lite describes the output of many of their inverters as PWM (Pulse Width Modulation) sine. I understand that Pulse Width Modulation, when done well, can much more closely approximate a sine wave. Do you think these inverters will perform well with the bose towers?
