Conclusion: Have these in 2 different vehicles. One car is using an Alpine 4 channel x 50watt amp to power them and the other car is using a factory head unit. The one with the factory head unit powering it sounds better than I thought it would for such little power a stock head unit has to offer. The ones in the other car being powered by the alpine amp sounds crystal clear even at louder volumes. The sound is very controlled while not being distorted.
Summary: These speakers are okay. Not top level speakers by any means. If you've listened to high end quality speakers then you will definitely notice the difference with these. I'd rank them in with if you just wanted something to listen to, did not want to spend a lot of cash on them, then these might be okay. To get the best sound out of them I feel you really need an eq to try to overcome their frequency short comings.
