It's usually not the speakers fault. It's usually
them clipping the input signal to the amplifier
that's causing the speakers to blow. Square waves
in an audio signal is NO GOOD!
To add to Matt's input (no pun intended), it's usually the tweeter that bites the bullet from clipping. The leading and trailing edges of square waves produce a lot of ultrasonic noise because of harmonics, and these high-frequency signals overheat the tweeters' voice coils.
Especially if there is more than one pair of speakers, I might suggest a separate (possibly multi-channel, if there is more than a single pair) amp to power the outdoor speakers. This way, the power delivered can be both regulated and assured to be up to the task.
