For the price, these are just fine. They brought a high level of clarity to my stock head unit. These have a lot of treble built into them, and not a whole lot of bass. Had to reconfigure my head unit's settings dramatically from the factory paper speakers. Overall though, a much better sound.
I rated the 6X9 in the same series a star higher, because these have a very low wattage rating and don't push a lot of volume. Doesn't matter with the windows up, but there is a large difference with them down. Also, I would've gotten the 6X9 as well for my front doors instead of these had I known they would fit, even though Crutchfield says they wouldn't. I was surprised to see 6X9's from the factory in the front doors.
Pros: High clarity, good price
Cons: Low wattage, low push, low bass potential.
