What do you want to know about a HeadUnit?

How the amplifier works? AM/FM Tuner? CD Player? Pre-Amplifier?

well i need to know HOW IT WORKS, like how its programmed, basically what makes it function.

i searched google but i just keep getting directed to small audio depot spots.

Well there probably is a central control unit in most of today's Digital Headunits.

If I had to guess.

CD Player Data (OR other Audio Data AM/FM/AUX) -> (A/D Converter for analog signal) -> Processor -> D/A Converter -> Output Circuity

Then everything is controlled by a Central Processor aka the brain of the system.

Pull one apart, look at it, and try to trace where all the signal goes. You might be able to figure it out.

They might use a completely different process. But, if it has EQ/Crossover/Time Delay I would almost bet it goes Analog->Digital then Processor then Digital->Analog then to a OpAMP Out. //content.invisioncic.com/y282845/emoticons/imdaman.gif.bc6c552e19aa4ad8c47461144f40eb1a.gif
