Summary: The speakers were perfect for my '04 alero. Fit like a glove. They were very easy to install and sound excellent. I only wish I could have afforded to replace my Power Acousik 6x9's at the same time because I'm certain Kenwood 6x9's would sound much better.
Conclusion: I would not recommend these to anyone. I have alot of Kenwood stereo equipment but these were the worst. They have a maximum power of 60 watts and they are the only 4x6 Kenwood makes but they wasnt worth the effort to put them my car. I had them for 2 months and one of them had quit workin and they other one kept playin.
Conclusion: These little speakers really project. I'm running them from my head unit, and I must say, they really fill in any gaps I had. I can hear the crash of the symbols, and really crank it up without distorting.
