Asking this question for my dad. He bought a 544 just like the one that he had when he was younger and I'm going to help him with the audio, when I get back to see him. He isn't quite sure where the speaker/speakers are in the car. He wants to keep the car as virgin as possible so I was going to replace the stock speaker/speakers in the stock location. We are going to keep the factory radio though and put the CD player in the glove box so you can't see it. If anything I was going to put some speakers in the bottom panels just forward of the door, and maybe some in the rear but I'm not sure about space or looks. Any info anybody can give me would be awesome. Thanks
