Well, those two amps may or may not be good for you. If you're running only one sub then the Audiopipe is a good suggestion. If you want two subs, then the MB Quartz would be a good suggestion. You would want to bridge the amp and wire the coils as 1ohm and run each sub on one output. You'll only be getting 500watts RMS but that's still quite a bit of power.
Now, what he said about sitting in the car with it full blast, that may not be true. But then again, they really are some good subs. I also wouldn't run any stereo at full blast.
