I have got a 6.1 amp. I set up the single rear speaker and the sound was a bit thin, so I jumped another (identical) speaker off it and placed them about a metre apart. Now to me this sounds much better than just using the single speaker. The only way I can describe it, is that the sound is wider. The question is this - if I continue with this set-up will I damage any of my hardware? Either the speakers or the amp. Cheers fellas.
