Summary: I have installed many stereo systems and these have disappointed me. I bought 3 sets to place in my Yukon and only one set worked. yes just one set and that set was very unclear and not worth all the work put into having them installed.
Conclusion: Keep in mind that when you buy these, you're going to have to push some power to them. They need more than your cheap 30rms 2-ways. That being said: These speakers ROCK! I've got a pair of these in the front and a pair of pioneer 2-ways in the rear. I've got the fade at six favoring the front to equalize volume, and these things are so freakin' clear it blows my mind. Installed right, they'll keep you happy. Take the time to tune! Recommended!!!
Conclusion: Power Acoustik this company is a joke. I will not buy another product from power acoustik. I have ordered and installed many of their amps and have no complaints, but these components are terrible. I have them hooked up to a 100w rms per channel amp and they dont sound nearly as loud without distorting as a pair of infinities in my read deck, which were only rated to 60w rms. A little over a week of ownership, the tweeters developed an annoying screeching sound.
