Sprout

I live in a fraternity house, also I am a novice, and have a pair of RF-7s; we have tailgates every Friday and play loud music and grill out. My Onkyo SR600 cant put out enough power for the tailgates. I recently hooked the speakers up to a Tsunami HQ2002s amp putting out 980 W per channel into 4 ohms. If I run this continuously am I in danger of blowing the speakers? If so any recommended settings for the amp so I can use the speakers with it? Sprout
