i have been searching forums and cant find nothing with this exact problem. i have been having a problem with my ML stereo system, i have a 2007 Lexus Ls460L, like a week ago my driver side door speaker was going in and out then it just cut out completely, 3 days later all my door speakers and sub went out but all my highs are still on playing normal i see post saying the amps go bad but everyone says a chirping noise or no sound but i have sound but only in for my highs i have no bass at all please help if anyone can thank you

 

I would take it out, send it the ML Amp to United Radio for repair. You can also called them for a quote, they can also diagnosis it first and let you know what the issue is before repairing it.

 

I suggest you let the Lexus dealership handle the issue with your ML stereo. My amp went out and the only sound I could hear was the loud chirping noise and it wouldn't stop until the Lexus dealership disconnect the amp in the trunk, and ordered a new one. The new amp/installation ($1000) was covered under my extended warranty. It may not be your amp since you still have sound. Keep us posted.
