We have a TV and two rear, in-ceiling speakers in a large bedroom (we should've sprung for the whole package when we built the house). The speaker wires run to the TV. We don't need a full blown Amp with all the bells and whistles. Is there something out there that will connect my TV, the existing speakers, and add front right, center, left and maybe a wireless subwoofer, so that I don't have to run wires from one side of the room to the other? Any suggestions will be appreciated since I'm not an Audio expert (just a guy with a TV and two ceiling speakers - smile).
