They are okay in quality. The biggest problem with them is that people's legs and feet block a good deal of the sound coming out of them, so you don't really hear them as well as you could. I far prefer using the factory mounting locations or fabricating something higher up in the door for better imaging. If you absolutely have to have 10 or 12 speakers in your car but don't want to pay some one to do the fabrication on it then I would say go for it.
