I replaced my front speakers with 3 1/2 inch Alpines. They had tweeters but did not stick up past the lip so they fit perfectly. Depending on what you want to do, I added a custom built shelp behind the seats and added 2 6 x 9 Eclipse speakers and 2 10" Eclipse Subwoofers in the customer shelf. I also left the stock radio in and added and Alpine unit in the custom unit between the seats. Then I added another set of front speakers in some kick panels. I have 2 Kicker amps (1 800 amp and 1 400 amp) in the trunk and a capacitor to drive the subwoofers. All in all I like the setup, great lound sound with good quality.
