Start a mobile sound system?
I have to put a sound system in a trailer largeish July 4 for a float. How I can get the power to a mixer, an amplifier and speakers without being connected or using a generator?
Can I connect to the towing vehicle? If so, the use of an inverter to convert 12VDC to 120VAC to power your computer. Use an amplifier to operate directly from 12VDC.
