Are you running active, and how? Tweeters need to match the woofers, so what's the rest of the system like? A-pillar would be my favorite location. I did door sills on this car but retrospectively, I would have rather done the A-pillar. Keep in mind, anytime you install the woofer separate from the tweeter's location, you are introducing pathlength disparity which means you need to control the time alignment between the woofer and tweeter, and the left-right disparity as well.JohnnyUtah said:Any suggestions on a good set of tweeters and the best location for install?
