Well these are just laying around in my closet...and basically whats left of my car after it was totaled a couple of months ago. These should fit right into your factory pillars (04-06). Not sure if they'll fit the 07+

They're basically the factory pillars re-wrapped in tan suede. Then a cutout was made with fiberglass work to fit my DLS tweeters on-axis to the driver seat so that the sound stage was aimed right where you'll be sitting. These took a ton of time to adjust and what-not so that I got the best sound imaging possible at the driver's seat. THE ANGLE OF THE TWEETER PODS VARIES FROM DRIVER SIDE TO PASSENGER SIDE so don't be alarmed if they're not identical. Those who know me knows I'm quite serious about my audio.

Anyhow, the diameter for the tweeter cutout is 1 7/8" with a half inch lip all around.

Looking to get $200 shipped OBO.
