Isudar PX6 DSP Problem Subwoofer OUT

[Meefek]

Hello
I have a Isudar PX6 DSP.


I have the amplifier connected via RCA to the 'Subwoofer Out' connection on the radio.

Everything works OK at first, but after shutting down (turning off car/leaving car), the output is not working. I can hear the subwoofer just 'throbbing?' But no respons.

Only way to get it back to work again is to disconnect the radio from the car and reconnect it. (Now i am taking out the car's radio fuse and putting it back in).

Can anybody help me with this issue ? ? ?

MCU Version
MTCE_GS_V3.44_3

RK3399 - Android 10.
Thanks in advance

Open the App Sound and adjust a slider briefly. After that it should work again.

I have the same problem. How did you connect the sub?

On the radio Sub output i connected a split wire (1 rca male to 2 rca male) and then in the Pioneer ts-wx130da line L and R cables.

Hello, I have a PX6 rk3399 1280*720 DSP MTCE_LY_V3.52_1 , and the problem I have is noise in the speakers, when I set the sound to 0 the noise is removed, but when I raise the volume to 1 it makes a noise like interference, that noise is always the same from 1 to 20, I leave you a video with the noise, I put it at 0 and 1 if you hear how it cuts and comes back.
it has a solution?

None of these units are MTCB.

All of these topics discussed in MTCD forum.
There is no fix, it is a hardware design defect.

This is my MCU I send it from the seller, my radio is from ISUDAR, I don't know if it will work for you.
