Trust me you would want these things as FAR away as you can get them, they seriously nearly deafened me. I HAVE to run the amp at it's quietest and even then they are loud, they are a teeth shatteringly clear type of loud too. If you put them in the pillars you would be deaf really quickly, no joke. and in the A-pillars I think they would still sound too close. If I could I would stick them on two poles extending 10 feet in front of the car and remove the windshield, but that would look retarded now wouldn't it
