Hello all, I have a 08 ls460 w/ premium audio. Recently this weekend I got into my car and noticed no audio from anything. Turning on and off the radio makes speakers pop. I DO NOT have mark levison radio or amp. Unhooked battery and Lexus amp. Waited an hour or so, hooked all back up and boom all working again. This morning radio works perfect,, going to lunch no audio again. Time for an new amp?

 

Some folks reported seeing water ingress near their amp in the trunk, have you checked to see if yours is nice and dry?

 

dry as bones in there. just reconnected the battery and radio works again...but for how long lol :/

 

update.. radio not working again.. ordered new used amp off ebay with 90 warranty money back guarantee.

 

Good luck man, let us know how it turns out
