What rumble said.
Just take the headphone or line out and feed it to an amplifier. The Beringer is great but I think an integrated amp or reciiver (which is an only integtrated with a tuner thrown in) would be a bit more flexible. Also, you'll most likely find you need subwoofer since those wall mounts were designed with one in mind and will sound, well, thin without one and the proper integated would afford that flexibility, as well as more control options. Perhaps one with pre outs and main ins, or perhaps a sub out. As far as integrateds go, I like NAD. They handle low impedances quite well.
