Looking for input on sound systems

[70chev20]

Just a thought, most of the stereo imaging in music comes from the very high frequencies, so I would be willing to bet if you installed one of those dual center speakers like retrosound sells in the stock location, then put some small tweeters on top of the dash at the sides of the cab, and some good 6x9s under the seat, it would be pretty hard to tell that there's only one full size speaker in the front. That way you get stereo sound without having to cut holes for speakers and it would be almost stock in appearance.
