I have a friend that has a mid range Harmon Kardon receiver with mutltiroom outputs. In his billard room, he has two simple in-ceiling speakers that the builders have run cable to his entertainment center for. Obviously, he needs to run his multiroom outs to some sort of amp, and then the amp needs to power the billiard room speakers. Does anyone have any recommendations for a super cheap amp that can handle some music from his receiver? I've been looking around but all I've been finding are 5 and 7 channel amps that have been costing more than his receiver.
