Summary: It was a good choice to replace the stock speakers in my wife's 2000 Jeep Wrangler. It has an aftermarket stereo but I am not sure it can push them as very hard. An amp would probably make them sound better.
Pros: Great sound for the money. Easy to install with the supplied adapters from CF. My wife is happy and she made me happy after installing them if you know what I mean...
Summary: I purchased these speakers to replace my cheap rear factory speakers when I was upgrading my system. I have a good Pioneer receiver and these speakers did sound a bit better than stock but once I hooked up a amplifier they really came to life. So far being amplified they sound great and are holding up well.
Pros: Low cost and sound great with a amplifier, they hold up well and bring out the sound.
Cons: Need to be amplified to really bring out the detail in music.
