Will a 1996 bose system (Speakers, cd player, so on) work on a 1992 bose system car?  Or are they totally different?

My back 2 speakers amps are shot and someone local has the whole system minus the pre amp for sale.  His is the cd and mine is a cassette so this would be a nice swap.

I'm also curious.  I bought a whole delco bose system out of this guys car (was a 95 vert) for 100 bucks (Killer deal I know).

The back 2 speakers that I needed fit perfectly and I noticed the amps had black capacitors while my older 1992 amps had green one's.  Are the 95 capacitors better/more reliable or are they basically the same?
