Request a Lexus Car Radio Stereo Wiring Diagram

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. Automotive wiring in Lexus vehicles are becoming increasing more difficult to identify due to the installation of more advanced factory oem electronics.

One of the most time consuming tasks with installing an after market car stereo, car radio, satellite radio, xm radio, car speakers, tweeters, car subwoofer, crossovers, audio equalizer, car amplifier, mobile amp, car amplifier, mp3 player, ipod or any car audio electronics is identifying the correct color car audio wires for your Lexus ES250, Lexus ES300, Lexus ES330, Lexus ES350, Lexus GS300, Lexus GS400, Lexus GS430, Lexus GX470, Lexus IS300, Lexus IS350, Lexus LS400, Lexus LS430, Lexus LX450, Lexus LX470, Lexus RX300, Lexus RX330, Lexus RX350, Lexus RX400h, Lexus SC300, Lexus SC400 or Lexus SC430 headlight bulb size you need for your low beam or high beam and save time. Also, find your other car light bulb sizes including your fog light, reverse light, turn signal, brake light and more. It’s that easy!

  3. Looking for wiring info for a 2012 Lexus IS 250.. I’ve located the factory amplifier in the right rear area of the trunk, but not sure which wire’s to tap into for my line out converter so I can add an aftermarket amplifier and subwoofer. Any help would be greatly appreciated.

    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.

  5. 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.
