I replaced all (4) stock Infinity door speakers with Polk db651 6.5" Coaxial Speakers. WOW! I can not believe the difference in sound quality. These speakers are crystal clear. They handle to the power (volume on 35) from 385W stock amp with NO distortion. Low frequency response is better than the factory speakers and the mid/high ranges are amazing.

The door panels were very easy to take off. Open the two trim covers (behind the door pull and door latch) and removed two screws. Pop off the entire panel buy tugging on the panel from the door hinge side. Swing the panel upward from the bottom and lift straight up. I left all the harnesses connected and had enough room to remove and install the new speakers. You will need the mounting kit that comes with the speakers to fit the Chrysler opening.

I purchased the Polk speakers from Circuit City. Buy one set, get second set 1/2 price.
