I'm worried about blowing my speakers now though

A more powerful amplifier is not more likely to blow your speakers. In fact, it is less likely.

Don't misunderstand: it IS more capable of blowing your speakers, but that's only if you're silly enough to crank the volume up to unreasonable levels.

A more powerful amplifier means you can attain the same volume from your speakers at a lower amplifier gain setting. This means you are less likely to send a clipped signal to your speakers, and it is clipping that blows speakers.

You could connect a single speaker to a 50,000 watt football stadium amplifier, and as long as you didn't try to make the speaker deliver more decibels of sound than it was physically capable of producing, the speaker would be just fine. You could connect a 50 watt amplifier to the same speaker and run the gain up so high that it was clipping, and fry the speaker.

Whether you blow your speakers or not isn't a function of how powerful an amplifier you have, but of signal quality and how loud you try to make the speakers play.
