Upgrade speakers for non JBL question

Hi ya'll,

I have a 2009 with a non JBL stereo. I have been looking on crutchfield to upgrade the stock door speakers. Since the Prius has those small tweeters at the top of the front doors should I upgrade them as well? Also, the upgraded speakers I found have both woofers and tweeters. Will that work with the small door tweeters? I'm an audio novice, just looking to get some better sound out of the stock radio. I'm not sure if the stock front door speakers have woofers and tweeters, or if they are just a woofer. I hope this makes sense lol

Thanks a bunch,

Mitch
