I doubt the deck puts out that much power... 30-40 RMS is probably what they're being ran out right now. I wouldn't really worry too much about how much power your deck is putting out, you should be more concern with the ohms that it's being ran out. I just sold some speakers to a camaro with blown speakers, he had a monsoon system, which is a pretty good stock system, however his speakers and system was wired to a 2 ohm load, so even though he picked up some descent speakers, his power was pretty much cut to half, and his volume wasn't as loud anymore. So I would check that out first, before making a decision on your speakers.
