Front-left Speakers Shut Off Sometimes

[yl1826]

Has anyone experienced a problem with their '08 RX 350 AWD sound system where the front-left speakers will shut off sometimes when hitting a small (very small bump)?

What should I be checking to fix this?

I have a semi-similar problem. My speakers drop to a very low level for a random period of time. The drop in volume has nothing to do with a bump and it is annoying. I brought it to Lexus service and they discovered a defect in the amplifier or radio head so they are replacing it in a few days. Just bring it in and let them diagnose it, that's what warranty's are for. Good luck.
