2020 Tundra 1794 Edition and No Rear or Center Audio


  • I've had great success with a Dasaita unit in my FJ Cruiser and desided to get the QCM6125 for my 2020 1974 Edition Tundra. The install went well, all the more complex things work, however I have no rear or center channel audio. When looking over the wireing I notice the speaker cables in the harness doesn't seem to match up. There are only 3 pairs of cable from the truck going to the harness, the the colors don't seem like they would match up right anyway. The 1794 Edition does have the JBL sound system; 9 speakers and a sub. The left and right channel work, and the sub works.

    My version details are as follows:

    Kernel version 4.14.190, #139 Mon Dec 23 18:41:45 CST 2024

    Build number zst27_QCM6125 13 S10A_123 eng.hct.20241223.182400 NA

    MCU version MTCHS_HA4Z_V4.15a_1, Nov 14 2024 15:38:58

    Hello.
    Thanks for your message.

    We suggest that you can try to go "Amplifier App > Delay > Auto > All" to move the crosshair to the center,
    then check if all speakers have sound normally.
