Here are the ratings for that amp.
300x1 @ 4 ohm
600x1 @ 2 ohm
1000x1 @ 1 ohm
I certainly wouldn't call it one of the most powerful amps in its class. For a 1 ohm stable amp, its actually on the weaker side. I'm not trying to bust your bubble, just trying to be realistic. The Alpine Type R can handle 500W @ 2 ohm, which means this amp will be perfectly suited for one Alpine Type R unless you ran two of them in a 1 ohm configuration. I've always heard its better to overpower your sub than to underpower it. That'* your call to make, but I personally would run only one sub off of that amp.
