Who has the best stereo equipment?

[DOOM]

I'm about to purchase the stereo equipment for the Camaro. I told Troy I'm not about the big sub boxes ,amp racks, ect. I like nice clean sound nothing obnoxious . I want a head unit with nav ,we are going to use one sub so Troy wants a Five channel amp and good quality speakers. The amp and sub will all be hidden I don't like this stuff showing. What is the best on the market for these items. I don't want any junk KRACKOMATIC crap! Let me here what you guys think. I haven't purchased stereo equipment in years.
