h1ckman, glad to hear you like your speakers. Don't fret over the 600 for right now. It's really easy to make a good sub sound bad if not dialed in. You'll have to spend some time with it once you get everything placed. Subs are very frustrating at first because they require a lot of fine tuning, but once you get it set it'll be awesome. Bypass the crossover on the sub and use your receiver to handle that part. Turning the gain up too high will make it sound boomy. Remember, be patient. I know it's tough, though.
