Summary: For all of the folks who want a clean, rich, full bass tone - these are great! I have 1" tweeters in the doors and 3-way 6x9's in the back dash. After I installed these I get a bass sound that fills the car. It completes the sound. I've seen people write about sounding tinny but I think they are finally hearing notes they hadn't heard before.
Pros: Fit perfectly - wired in parallel with door tweeters coming off a four channel amp. This makes wiring and power supply simple and effective.
Cons: I would like to see them handle about 5-10 more watts and come without a tweeter.
Summary: I hate to say this after spending this kind of money, but the factory speakers in the rear of my 2011 Chevy Express van sounded better than these. I realize that, due to the cavernous space, a 4" speaker won't provide the performance of a larger speaker, but I was expecting more than what these provide. There is no bass response and an overall tinny sound from these speakers.
Summary: I purchased these speakers around 8-9 months ago. I installed them into my 2006 Jeep Wrangler Sport and wired them onto my aftermarket head unit (50 watts per speaker) quite painlessly after a quick delivery from Crutchfield. After a few minutes of listening I quickly noticed 2 things. 1. The highs and mids were of AMAZING quality 2. The speakers shake a LOT when the bass boost is anywhere from -2 to 12.
