I have an '88 k5 with the stock stereo,and its in bad shape. The problem is that I know zero about car audio. All I want is to have a clear sound at med to high volume without blowing my eardrums, without alot of bass and without alot of money. I talking about a fairly decent radio and speaker combination that I can buy from a discount store like Best Buy. I see alot of 4x45 and 4x50, what does it all mean? I just want a simple but decent system. Please help.
