Fosi is a trash company that makes trash products. I regretibly purchased one of their amps over the holidays. Had to download a third party software to remove the godawful silence detection so audio doesn't sound like dogshit everytime a talking scene takes place. Settings won't even save so everytime I turn the amp off I have to reset the settings. Never ever ever by this trash.
