Amplifiers can be too powerful for speakers. Speakers are limited by the electrical energy that they can convert into audio. As a general rule, if the amplifier produces more electrical energy than the speakers can handle, it may cause distortion or clipping, but damage is unlikely.
Can subs ruin your alternator?
Subwoofers on their own cannot damage your alternator. However, subwoofers combined with their amplifier and the corresponding amplifier can damage your alternator if it draws too much power from your battery. And this can cause the alternator to overheat and potentially damage.
