I recently bought a Glow Amp One (http://www.glow-audio.com/Glowamps.html) which came with two glow speakers and no subwoofer. I thought it would be easy to add a subwoofer but I was mistaken. I have no idea what I'm doing with this machine- I'm looking at purchasing these speakers (https://seattle.craigslist.org/see/ele/5730621429.html) and I need to know if they are compatible with my Glow Amp and how to connect them. I am not sure where to look for advice, any help would be appreciated. Pictures are of the Amp's stats from their website, the back of the amp, and the back of the speakers I'm looking at buying.
