Good Speakers
I have heard better component sets, but these are pretty good If you are a little tight on money. The only problem I had was that some water got into my door panel and got up into the speaker. Not a problem with them, just my fault for not using speaker baffles. I do wish that it had adjustable crossovers though instead of just some inline bass blockers.

Good product
Put two pairs of them in a El Camino with a powerbass 300.4 amp and they screamed.

Great for the price
I just put these in my Buick Century and they sound amazing. i do not even have rear speakers yet and the car sounds like there is a 12" sub hiding somewhere. The tweeters sound great and I have been hearing things i have never heard in my music before.
Bottom line....great speakers at a great price.

Pretty good
This was a good set of speakers for my replacement of a 6-speaker Infinity system in my Durango. These sound great running off of my Kenwood HD head unit.
