Hello all-

The most recent repair to the STR was a new EGR valve. First thing first I disconnected the battery. Once the repair was completed I re-connected the battery and heard a slight "pop". When I fired up the vehicle the audio has no front speaker response. The rear and the Sub work fine but if I fade to the front..there is nothing.

Any thoughts?

Thanks in advance!

Mark.

 

As the audio to the amp is linked to the head unit via the optical link it is unlikly that it is a fault with the head unit.
It may be worth checking the setting in the head unit, including the DSP setting that should be on 'all seats'.

Did you get to the bottom of this ?
