Well, anything's better than a blown speaker...
What's your budget? Kickers are okay but they're in the budget (cheap) bracket.
Also be aware that the amps aren't great. They do good for the stock speakers and units with similar specs. If you want good sound and put in good speakers, you're gonna need to do other upgrades.
But, again, if your speakers are blown, just replacing them with anything will be good. Either pick up some factory replacements on the cheap, or have a look at what Crutchfield recommends.
