First off, I would like to say that I really have zero knowledge with regards to car audio. I just got a minto 1990 Mercedes 300SE. It has the Becker stereo with cassette which is being replaced by an Alpine cda-9833. Until I have a better plan, find a quality installer, and have plan, I want to use my stock speakers. I have no idea what comes stock, what size or how many. I want to power then via the head unit for now.
As far as upgrading, what is a good game plan? I don't really know the difference between components and coaxial or what I should be looking for. at some point I will probably add a sub in the back. I am looking for good, quality concert sound. Not bass heavy, pounding. I want the car to remain stock in the looks dept. Can anyone give me any ideas?
