Tweeter placement
 

Hello all,
Please forgive me for not posting in a long time. I really haven't had any super cool audio projects lately. (although I am almost done with a monster F250 show truck)
Anyway, I am doing a mild system in a 2010 Toyota Tundra. I bought a set of JL Audio C3-650. They seem really nice. In the Tundra I have a choice to place the tweeters in the sail panels behind the mirrors to have them face me or in the upper front corners of the dash and reflect off of the windshield. Opinions? Please discuss. Thanks

you have to be carefull on the distance between the mid and tweeter

here is a chart....... if you read the notes it's easy to use
