Exploring the problem of popping sounds

Skillzo1

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

I installed the public release.

jpapadami The public version cannot update MCUs belonging to DUDU.

Thank you for the info.

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.

Janebo Shooting version information

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.

Janebo

dudu-lai The system is ok on startup, no pop sound, the sound is appearing on shutdown to sleep or shutting down to off modus, ignition off,

dudu-lai

Janebo Are you using the RCA low-level or high-level audio from DUDU?

dudu-lai

Janebo Hi, please record a video of a popping sound after the shutdown.
Could you reproduce the issue multiple times and upload the recorded video to Google Drive and share it with me for download?

Ja. Und es nervt so sehr. Bei beiden Autos knallt es so laut. Dass wir Angst haben, dass unsere Lautsprecher kaputt gehen.

Janebo

dudu-lai I am using the RCA Low level for subwoofer and for front and rear speakers, using the blue wire, Amp cont for controlling the aftermarket amplifier,

I don't know if this is possible: if the software allow to turn off the Amp cont wire 1-2 seconds delay before the unit power down, then there will be no power at the amplifier when the pop sound is happening
