Whether your an expert Lexus mobile electronics installer, Lexus fanatic, or a novice Lexus enthusiast with an Lexus, a Lexus car stereo wiring diagram can save yourself a lot of time.

  6. Where on the fuse panel (below left of steering column) can I get constant 12V? The constant 12V in my 1996 Lexus ES300’s wiring harness has no power to the radio so I’m going to power it from the fuse panel. Must be constant 12V. Thanks

  7. 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.

  8. Mike, you would have to install automotive auxiliary input adapter. An automotive auxiliary input adapter will allow you to input any mp3 player or portable music player into your factory radio. This is the easiest and most cost effective way to add an audio input into your factory stereo. Here is the adapter you will need:

  20. I want to install a subwoofer amp in my 2000 Lexus RX300 and was wondering about getting through the fire wall, any suggestions?

  21. David, most vehicles have a factory hole with a rubber or plastic grommet at the firewall. This is usually the standard place to run a power wire through the firewall. If one of these holes are not available or not large enough, a hole will have to be drilled to accommodate your power wire. Choose something on the engine side of the firewall as reference and try to match it up on the interior side of the firewall. This will make sure you do not drill through anything important. Then drill a hole somewhere near or beside your reference point. Make sure to use a firewall grommet to prevent the power wire from chaffing on the firewall that could potentially cause a short. Hope this helps. Good luck with your 2000 Lexus RX300 amplifier installation.

  25. I have a 2008 Lexus IS250. I want to put a 12 inch polk audio sub with a box in and a polk amplifier. Is there a way I can this.? Are there RCA’s behind the radio or do I need to get the box to hook up to the rear speakers. any help would be great.

  26. Joe, most late model vehicles do not have RCA inputs in the back of the factory stereo. You will need some aftermarket electronics to hook up a subwoofer to your 2008 Lexus IS250 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 2008 Lexus IS250 amplifier and subwoofer installation.
