  1. I was wondering if you knew if the Mark Levinson radio is a direct replacement for a non-Mark Levinson in a 2009 Lexus RX 350. I did notice two blue plugs on the back of the Mark Levinson radio compared to a non-Mark Levinson radio. Thanks for the help. anyone?

  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.

  4. 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.

  8. I am looking for the in-stock radio wiring diagram or colour codes for my 1999 Altezza model RS200 an equivalent to the 1999 Lexus IS200 model.

  9. 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.

  21. I need the speaker wire diagram for lexus 2006 sc430. I am trying to install a line out converter behind the radio head unit. I have search several places that say wires (green/red) for left speaker and (black/white) for right speaker. I’d tapped my line converter device into these but is not getting any signal. I really don’t want to install the line converter at the amp that’s in the trunk because i would have to run an RCA line to the front. The reason i need the line out at the front is because i’m installing an Equalizer. Thanks alot.

  22. 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:

    Auxiliary Input Adapter for 2001 Lexus ES300

    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 2001 Lexus ES300 aux input adapter installation.

  23. 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.

  24. 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
