i need an invertor / inverter so i can use my car audio amp at home.

it does 1kwrms at 14v, at 1ohm, but ill be using it at 4ohm. i need an inverter that plugs into the mains and has power outs so i can wire a 4gauge power wire from the amp to the inverter. only i can only find inverters that let you use laptop or home hifi in car. any help please ?


cheers, J
