Thank you both for your responses.
My next question was if I had the speaker wires connected properly. The manual is a bit confusing. It states "The single set of speaker conductors are connected to the LEFT and RIGHT (positive/red) output terminals. In this special case, the LEFT terminal acts as positive and the RIGHT terminal acts as ground. "
I wasn't sure if they meant the red terminal on the left side on the rear of the amp or if they meant the terminal actually labeled Left. This is because the one actually labeled Left is on the right.

Anyhow, I figured it out myself after looking at the image I linked to. It has small positive and negative symbols next to each terminal marked Mono. Guess I would have seen that if I was wearing glasses when I hooked up the amps. Oh well, I'm adding this for any other person who may read this and is as half blind as me.
Again, thank you folks for the replies. I'll ask more questions here than I can answer but I will provide anything I can, especially if I think it will help out my fellow novice audiophiles.
