I just purchased the 5 1/4 DB575 for the front and 6 1/4 DB650 for the rear of my Toyota Corolla. They're powerd via a Kenwood 200watt cd player. They're much clearer than stock speakers & really like them.
Just one issue; Some of my music has a lot of bass to it & I have to turn the bass almost off to get decent sound from them.
Am I missing something in my configuration? If different speakers would fill my needs, please let me know.
