    NO POWER

    Stock stereo was replaced 2 years ago & the aftermarket one was working fine. For some reason in the winter it had power and all functions displayed but there was no sound/audio. Even though the illuminations on the display flashed to the music like it was still playing. A friend advised me that something was shot inside that powered the audio out. I tried 2 faceplates for this radio because someone I know has the same stereo. My faceplate worked on his, but his had the same “no sound/audio” in my car.

    So I just bought another aftermarket stereo but the radio constant 12V from the Lexus wiring harness doesn’t seem to have power. Factory harness didn’t have power either after the no sound issue occurred. I can get power from the fuse panel with a spade tip wire to power the stereo, but this is not a constant 12V so the clock & pre-set radio stations will constantly need to be re-set. This would drive anyone nuts so you can see why I am looking for advice.

    How/where can I get a constant 12V? Can’t go direct to the battery cause that will blow the stereo. Is there a way to steal power from the factory wiring harness (behind the radio & climate controls) for the factory CD changer that I am not using? Or is there a fuse in the panel left of the steering column by your left knee that has constant power?

    Thank you for any advice.

    Lane, first double check ALL your fuses and make sure ALL your fuses are good. You can do this by using an Automotive Fuse Tester and making sure all of your fuses are not blown. If all of your fuses are good, run a wire to your steering column and use the white wire in the ignition switch harness. This will give you a constant power source for your radio. Hope this helps. Good luck with your 1996 Lexus ES300 radio installation.

    hey, i have a 1996 Lexus ES300. i really dont want to change head unit but i want to know if i can hook up an amp & subs to the factory radio dont know if the wires in car have remote wire or rca ‘s for amp connection. can anyone help?

    Luis, yes you can hook up your an amplifier and subwoofer to your stock stereo. You will need some aftermarket electronics to hook up a subwoofer to your 1996 Lexus ES300 factory stereo. You will need five components:

    1. Car Subwoofer
    2. Car Subwoofer Box to house your car subwoofer.
    3. Car Audio Amplifier that matches your subwoofer power needs and ohm rating.
    4. Car Amplifier Wiring Kit that can handle the power needs of your amplifier.
    5. RCA Line Out Converter to feed an audio signal from your factory radio to your aftermarket amplifier.

    First run all your amplifier power from your car battery to where you plan on mounting your amplifier. Next, run your ground wire from your grounding point to your amplifier. Wire up the RCA Line Out Converter to the rear speaker wires to get a full range audio source. Next, connect one end of your RCA jacks to the Line Out Converter and the other end of the RCA jacks to your amplifier. This will provide an audio signal to your after market amp. Lastly, connect your subwoofer to your after market amplifier using the speaker wire in the amplifier wiring kit. If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 1996 Lexus ES300 amplifier and subwoofer installation.

    I’m replacing the radio antenna on my wife’s 1996 Lexus ES300. Upon removing the broken old one, I discovered there were two antenna signal wires including the one I expected and one that was taped off and not used. The two wires were run next to each other on the way towards the radio. What is/was the purpose of the second (with a non-standard connector) wire? Anyone? Thanks! Gene

    Soo… I already installed an after market car stereo into my 96 Lexus es300 (installed it my self), but now when I set the car alarm on, after a few hours later the Alan goes off. Also the previous owner had already installed another alarm to the car. Another problem is that instead of the blue light blinking, its a red light not blinking at all. PLEAS HELP ME ON THIS!!!

    Johnny, it would be hard to say what could be causing your problem especially when the previous owner installed an alarm. Our advice is to take your 1996 Lexus ES300 to a qualified alarm installer and ask them to troubleshoot your alarm because it does take some wiring experience and alarm installation knowledge. Hope this helps. Good luck on your 1996 Lexus ES300 car alarm troubleshooting.
