Summary: Best speaker that I have had for front speakers in my jeep wrangler and I have tried a few. Good quality for good price. You could pay a lot more money for some speakers and still not get the quality of these.
Conclusion: I have these in a 2009 Aveo 5 with a kicker 200.4 and i have to turn the amp down to just below half or they dont sound very good. But at that volume they sound really good great highs and decent mids. The amp i am running at that gain setting they are only gettting about 45 watts i wanted to push them with the complete 100 rms but i cannot do that do to sound sound quality.
Conclusion: I decided to go with these speakers due to friends talking about how much they loved them, and am so happy i did. I still have to finish getting everything for my system, for now I only have the speakers, but those alone make a complete difference. Five stars.
Conclusion: ive been tinkering with car audio systems for 8 years in four different vehicles. I am no expert by any means. I have to say when i first installed them i was anticipating something amazing. i would say for about the first 2 weeks or so they werent as good as i expected. but after a while it seemed like i could turn it up higher and higher without any problems. now i hooked up a kenwood 4 channel running 60w x4 With 12g speaker wire. They really sound amazing.
Conclusion: I purchased these to replace the door speakers in a 10 year old Boxster, whose original speakers were no longer crisp and couldn't handle the bass at even moderate volumes. These speakers didn't sound any better than my worn out stock speakers. I ended up putting my stock speakers back in.
