I am on a budget right now and am looking to get an Infinity 12” 1200-Watt Subwoofer. I would just like some opinions on a good inexpensive amp for this sub.

U.S Acoustics makes excellent amps for the money. I'm guessing you have an infinity reference sub so I think you would only need something like the USB-2100. This amp outputs 300 watts bridged at 4 ohms which should be plenty.

4-channel means the amp has four seperate outputs and can drive up to four speakers. 2-channel means 2. Mono means one.
