Much like my front speakers, I had to install these with an adapter (2002 Subaru Impreza). I was amazed at the quality of sound to come out of these little guys! The tweeter somehow overpowers the front tweeters even though everything seems to even out at higher decibels. At first I got a lot of distortion and what sounded like the speaker colliding with the grille in the door at higher volume levels. However when I replaced the amplifier (Crunch P1 5000.5) all that disappeared. I forgot how good music sounded with a decent amplifier. I am SO happy with these.
