Hello Everyone,
I'm looking for some assistance. I have an 2004 RX330 with a stereo that emits an extremely high pitched whine - the frequency of the sound will change when moving the radio dial and reaches frequencies that my old ears cannot register, but others can hear it. The stereo itself appears to be fine - stations tune, CD/Tape will load & eject. The sound occurs whether the car is running or not running. I have had some instances where the high frequency whine will become strong static and one time in the past few months the radio actually emitted music but with extreme static - and then it immediately returned to the high frequency sound. I did some googling and I started focusing on the amplifier - I would be interested in whether others agree with this ? I actually got to the amplifier today, I removed the wiring harness plugged it back in - I got some static then back to a high frequency sound. Question - Does this sound like an amplifier issue ? I pulled it out of the car - is there a way of testing it ? should I replace ? Any thoughts, suggestions would be appreciated. Thank you
Amplifier = Toyota PIONEER GM-8337ZT
