I took out the head unit to clean the display from the inside. When I put everything back now there is only sound in the front and not the back speakers. What did I do? How can I fix it. All the ribbons are securely connected to the circuit board. Please help.

Okay, I opened up the head unit and everything seemed fine, but this time I connected it to the harness with the side panel open giving me access to the circuit board/ribbon. I had to test to see why this was happening. The white ribbon is what controls the speakers and what speakers the music come from. I had to wiggle it to where all 5 speakers were playing then snapped it in to the circuit board. I have the 99 GS 300, nakamichi premium sound system. I thought I needed a whole new head unit but after taking it apart and putting back together a few times, it's back play crisp and loud! Hopefully this will help someone.

Yes, the display got cleaned from the inside.
