Nick,
That '78 is beautiful! I can see why you are so proud of it. I have the original stereo in my '81 and naturally it sounds like crap. I have tried to keep everything on the car in its original condition, so I am worried about messing around with replacing the stereo and speakers. But I agree with you, a nice sound system is a must. I thought about leaving the stock stereo in dash, replacing the speakers with good ones but keep them hidden behind the covers, and hide a disc changer in the glove box, amp under the passenger seat. Those are my plans, but as I said, I am a little reluctant to do anything to the car that detracts from its original character. Thanks for sharing your site. I enjoyed it.
Sean
