I'm looking into getting a VP180, as long as my Yamaha RX-V659 can drive it (it has a 4ohm setting for L/R inputs so I'm hoping?)

Question is what to do with my current VP150. I just installed a plasma in my bedroom and the internal speakers obviously are lacking. Thinking of mounting the VP150 below it, connect an amp and run a downmix to it? Kinda like a poor man’s Polk/Yamaha DSP speaker?

Would this work?
