I have just purchased a '79 GTS and will be replacing the Alpine receiver and graphic equalizer (getting lots of static, plus I want a unit for MP3 discs). I assume these were probably dealer-installed, along with the in-door speakers and external tweeters/crossovers. Is the dash removal straightforward? I'll probably just get a powered head unit and save the external amp(s)/sub-in-kick panel/etc. until I decide if I really need more (and get braver about pulling apart a Ferrari I will also replace the speakers if the current ones don't work out. Thanks for any thoughts - it's an exciting car to own, and I've been finding a lot of good info here.
