I use long speaker runs and am currently getting some of the best sound I have had. As long as the gauge is at least 12ga you will be just fine. No worries about signal loss etc.....
I use 10 gauge. No loss of bass or sound quality at all compared to 8 foot runs as I have compared with my particular 10 gauge cable.
