I bought a 95 ls400 recently and i was driving it this weekend and the stereo sounded great. I shut it off and got out and when i started it back up there was nothing. Stereo turns on fine but no sound and the fuses all look good and i did check power to the amp and it was hot. Does anyone have any suggestions? I did see something about a phone but mine doesnt have one. Funny thing that it never even acted weird before it stopped, it was like someone muted the radio. Thanks with any help i can get. it is a nakamichi 50160 amp.
