I went with a "secret audio" tuner/amp that will be mounted under the rear seat, and a 10 CD changer thats mounted under the package shelf in the trunk. Rear speakers are 6 X 9's and for the front, i used a dual voice coil 4 X 10 in the stock center location. Thats basicly 2 seperate speakers that fit into the stock center speaker location. The tuner/Cd changer is controlled by a RF remote, and there is a small display head that will be mounted in the glove box. The factory AM radio resides in the stock location, but it's just a dummy unit. Once i get this all installed, future mods will include a amp for more punch, and a compact sub woofer that will fit under the rear seat. My goal here is an almost "invisible" audio system, so the car appears completely stock.
