Audio Systems: Car Speakers, toyota avalon, watt speakers

Question
I recently blew my speakers in my 1997 Toyota Avalon. I want to replace them with an affordable upgrade. What should I get, and how hard will they be to install? Should I leave that to Best Buy?
Also, how many watts powered the system in this car?

Thanks

Answer
i would first go to crutchfield.com and look up your make and model. this will tell you just what fits, depth of speakers and so forth. i wouldn't buy from them, they're too expensive, but they are a great reference site. your stock system is probably no more than 15-25 watts per side. i would go with 60 watt speakers, though.
