The guy that has installed all my car audio said the samething so that's what I'm having done now. He said the tweeters would cut out a lot of sound as opposed to quality 3.5 in speakers. I'm sure it will sound great but I kinda wanted to have the tweeters mounted. Maybe I can add an amp to power them for a custom setup... I have 3 sets of preouts on my Kameleon receiver.thump186 said:the a pillar is an ok place to mpunt them if they are in the arm rest i think they would be a pain in the ass covering them up and such. plus they would be screaming kinda close to your ear ANNOYING.... for a tweeter the dash is kinda a hard spot due to the windshield. the high sound waves will bounce off of it in wierd ways. i would go with your a pillar they are not quite as annoying and with still give you good sound staging and imaging. if your worried with mounting why not go with a pair of rockford fosgate 3.5 inch 2 ways they will mount in the stock location and have you tweeter and 3.5 all in one.
