I strongly dislike stereos in cars like this.... thats tuner crap in my opinion. Sorry, I want engine parts, not speakers. Just my opinion, but I dont think you're going to get many pics of sound systems on this forum.
I agree to a point - i have a cd player hidden and on the back shelf i have speaker grills out of an old 80s somethin that are round and look perfect. I got a set of 6x9s back there under the cardboard shelf, and now i get to listen to some music while i drive. I dont want a sub or anything crazy, because this car has got to look good, even in the trunk. Personally, I dont think that subs look natural in a classic like ours, BUT i think a stereo is important; and asking how people put stereos into their cars is a valid question.
True - he wont get a lot of pictures of some massive stereo systems from this crowd - but personally, Im strong to "Build it how you want it". Now, if he figures out how to put some massive system into his car AND make it look good - BIG props to him!!
