You feel thats crap and you dont even know how to pick an amp?
What are you talking about? Your subs can only handle 800 watts RMS, a 1200 watt amp is TOO MUCH, you will "blow it out" with that many watts. How do you feel "safe" giving your subs more power than they can handle?
Skip the 4 channel. Its for interior speakers! A mono amp is best, but what model are the CVRs? 2 or 4 ohms? This is real important when choosing an amp.
You need an amp that makes around 800 watts RMS.
