I have a 2007 aveo hatchback and am working on getting better sound so i am thinking about getting some tweeters but i dont want the wires to be showing nor do i want to drill or screw anything to ruin my dash or other panels. Where is the best location and technique to mount a pair of tweeters. Its just that the speakers in this car suck and i want to get more foreward sound cuz most of what music i hear comes from the back and it sounds like crap. Please help me any advice will be much appreciated.
