Exploring the problem of popping sounds

vos

McDudu Any improvements since your post to the quality sound? I have a HK system and am thinking of getting the head unit but seeing feedback like this is preventing me doing so and just sticking with OEM unit

McDudu

vos Yes, i have spent a lot of time trying different things and documenting the installation. one key aspect was that i confirmed the audio can be improved by controlling the Harman Kardon equalization via the CANBUS vehicle info app, and the Dudu7 internal amplifier power output via the advanced setting in the dudu7 soundstage (mixed of the two),. I created a detailed installation video series going over the installation process for Subaru Owners North America. and i am currently working on a walk through of the new 3.6 OS features. Search for Subaru Outback Dudu7 installation on youtube ..you would find a series of videos , where i documented the entire installation, you would hear a demo on the sound quality and basic Dudu7 (3.5 Dudu OS) functionality.

I also have this popping sound on a Mazda CX5 2019. My unit is specific to my car which I have DuduOS3.6 beta 5 installed and the original Mazda OS.

Is it save to update with the Dudu MCU in this thread so I can give it a try?

Are there any other improvements to this MCU besides the 5 sec amp delay?

jpapadami You will need to connect the AMP control wire to the DUDU's A connector AMP-C harness and update the MCU.

Thanks for the support. Unfortunately I am unable to update the MCU with the provided one in this thread. And yes, I am using the correct Dudu 4/5/6 version as my unit is a 7862 based unit running official DuduOS 3.6 250515

jpapadami Did you purchase the device from the official DUDU or did you install DUDUOS on the 7862 public release?

Still doing install here. Removed previous pioneer unit with all 4 interior speakers working. Upon installing dudu7 heard crackling in all 4 interior speakers at low volumn.

Driver front speaker is now blown. Not saying dudu7 did it but definatly heard the crackling sound and now the speaker is confirmed blown. Pretty sure it worked when pulling pioneer unit.
2008 toyota corolla ce usa no canbus. Dudu7 10" 4 upgraded interior speakers. 2 in front driver & passenger by lower feet 2 in rear deck.

jpapadami The public version cannot update MCUs belonging to DUDU.

Janebo MCU has been successfully updated. At this time, the AMP cont line of the A interface will output 12V voltage after 5S of booting into the system. If there is no effect, please check whether the connection is correct, or measure the voltage after booting into the system to see if it is valid.
