I want to hook up my amp to a 12 volt battery. I found an 12-110v inverter real cheap and I bought it for a Teardrop trailer I am building. I hooked it up to a couple of PA's and Amps and I get a HUM. I started reading and determined I hade a modified sine wave inverter and they can make electronics hum. Supposedly a Pure Sine Wave inverter is what I need. Has anyone hooked up a pure sine wave inverter to their PA/AMP with the result being no hum?
