Thank you for responding! I took out the CD changer and amp and started looking for a replacement amp on e-bay. Not too many for sale that match the model # on the amp. I will put them back into the car and then try your speaker test. Thanks again.

It could be blown (rear) speakers, especially if they are still stock. I had this problem and thought is was my amp. I would check/test the rear speakers with a cheap 2inch speaker you can buy at wal-mart. Take the trunk lining down on the passenger side/Cd Unit and locate/disconnect the +/- connections attach the working speaker to the +/- clips and turn on the radio and prey for sound. Here was my DIY First half to process: http://us.lexusownersclub.com/forums/index.php?showtopic=36346&hl=rear+speaker+replacement Second half:

One day the system stops working. It has a sound coming fromthe speakers like a skipping cd. Is the amp shot or the head unit or both? Any help would be appreciated. Maybe it's time to go aftermarket with the whole system? 1995 SC400
