@Support Dasaita I checked everything you asked. There's nothing muted and when set to Manual/All there is still a problem.
Checking more closely tonight, with these settings I get some sound from the left rear speaker but I have to put my ear right beside the speaker to hear it. The right rear speaker does not have any sound at all, even when sound is fully faded to RR.
@jose gonzalez Do you have factory amplifier?
please go to the DTS APP to check if the mute button is disable.
And please set to "ALL"and"Manual"to see how it work.
Have the same problem with Toyota RAV4 2017, rear speakers sounds very very low.
Order SP-DA7490
