I am looking at a '93 SC300 that has the factory cassette with an aftermarket Sony CD changer stuck onto it. I was hoping to find a car that had a factory CD changer.... My question is, do the cars with a factory CD changer have better speakers and amps than the cars without? (Nak equipped cars nonwithstanding, I know those have bigger and better stuff)

 

The speakers, amps and the head unit are exactly the same for the cars with or without the factory cd changer, with the normal Lexus Premium Systems. The cd changer was just a $900 option that could be added to the car.
