Speakers can't "require more power". All the ones I know are just happy with what you give them. The only thing to kind of watch is if the amplifier is capable of more power than the speakers can handle, you can rip the cones.
Yep - And you would probably notice the speakers sounding pretty distorted before they got loud enough to reach that point.
Some stereos will only accommodate a limited range of speaker impedances, so it's a good idea to use replacement speakers with the same impedance as the originals (i.e., if the originals are 8 ohm, use 8 ohm replacements).
Incidentally,
Parts Express has a large selection of speakers and installation accessories, at reasonable prices.
