Peaks At Vail Resorts I Wanna Get 3 Subwoofers With Peaks Of 400watts Each,so Does It Mean My Amp Needs To Be At Least 1200watts?

I wanna get 3 subwoofers with peaks of 400watts each,so does it mean my amp needs to be at least 1200watts? - peaks at vail resorts

I have two amps or 600 watts? Or am I completely wrong to do amps to power in a bit with the tips of submarine anyway?
