Hi folks. Just had the rear main seal and cam seals replaced by Lexus. Got the vehicle back and my radio turns on but the speakers do not work (a very faint sound comes from each speaker with the volume turned all the way up). I purchased an aftermarket Kenwood in May and it worked perfectly. Checked the radio fuse and dome fuse and both are good. Any suggestions?
thanks in advance

I believe the OEM amp cannot be used with any aftermarket HU. It has a very specific digital communication link (control interface) that cannot communicate with anything else. Your HU is probably connected directly to the speakers (bypassing the OEM amplifier) or has its own dedicated amplifier installed somewhere.
You need to remove HU from the dashboard and trace the routes of the audio output wiring harnesses.
