Yep. Auna /Hyundai rebadge.

check for dry joints around the volume control. or might be a dead ic that controls the volume for the centre and rears.

Them little knobs turn down the volume that control the center and rear. but the big main knob will only turn down the front.

I believe the back speakers and center speakers aren't even working at their max volume.

Re: Harman HA-7.1hd(stuck on the same volume)

Has it ever controlled the rear and centers?

Re: Harman HA-7.1hd(stuck on the same volume)

these people claim it has but I am unsure of that myself.

No manuals, No idea of how it should work sucks.

would swapping IC chips work if they are the same chip?

Re: Harman HA-7.1hd(stuck on the same volume)

Should do, assuming they are working & exactly same part.

Re: Harman HA-7.1hd(stuck on the same volume)

this might be a good test to see if the ic chip that controls the main volume of the rear & center is gone.

I will slip this out on the weekend.
