Amplifier issues
Hey everybody i've been on polk forum for just a little bit now, and haven't had a problem or question that couldn't be answered or fixed so i figured i ask some more, I current have SDA-1C's and i have them being run by a single GFA-555 (adcom), and i just came across a deal on two GFA-565 mono's i was wondering am i still going to have to worry about my single ground connect in order for my polks to have the sda effect? If so what can i do to help my situation?
