Android Phone as a Head Unit

I have read the posts on the Iphone hookups for a stereo in a cl***ic car....has anyone done the same with an Android phone ? I have a 65 Riviera and really dont want to have a modern stereo staring at me... BUT would like a really nice sound system. Can it be done with amps and other bits and pieces....I know very little about the whole process...I have a Motorola Droid that is way smarter than I am !!!

 

Out the headphone jack to the rca input on the amp. Do a search, its been covered a million times
