Speakers

[sawghost]

Hello, Im new at the community. I actually own the z506 sourround speaker system. I want to know if somebody could help me with these tow questions. First, now im not interrested using sourround sound, I work in my laptop an all 5 speakers are in my desk, 3 of them doesn't sound much because im using just one input so they are working in 3D stereo sourround mode. I want to know if I can unplug the sourround speakers and the center one without damaging the amplifier, just leaving the 2 front speakers. And second, the subwoofer makes difficult to clean next to it so i was thinking to put it under my desk, on a shelf, the problem is that the subwoofer if on that shelf should lie horrizontaly (with the cone facing sideways) would this affect the refrigeration on the sub?
