I'm looking to upgrade the speakers in my '06 TR, and was wondering if anyone had installed aftermarket tweeters behind the grills by the door handles. The stock TR config is a 5.25 at the bottom of the door with no seperate tweeter. Because all speakers sit low in the car, the sound sucks. Sounds like my tunes are playing through mud. I'm looking agt a Infinity component system with a 5.25 woofer down low and a 2" tweeter up. It looks like since there is already a grill that a tweeter install would be easy, but I just wanted to know if anyone had taken the door panel apart to se what's behind the grill. Thanks all!
