My car is Mazda cx50 2023 / without Bose sub option

Hi everyone 🙌🙂 I wonder anybody could help me there , because I end up with black screen installing JBL bass pro subwoofer .

So I’ve connected it and tested out with just taped by hands wire very gentle . It’s worked perfectly fine sound is great I should say 👌🙂

but than I’ve started to look we’re to connect 12 v remote wire and pull out head unit disconnect all connectors on the back , than tested by multimeter for power with acc off/on and ignition off on to see which one I would need. Than realize that it’s easy to take it from fuse box by using fuse tap connector . Finished everything … and head unit never starts since that … black screen and messages on the dash screen “In-vehicle Network Malfunction. Have the Vehicle inspected” and “Driver Attention Alert Disabled”.

I think it happened because I turned acc and ign on while head unit was disconnected and the car wind read it correctly now. Tried rest “mute”+”nav”+”back” - no restart . Checked head unit on electric issues - all good. Checked all cabin fuses - all good 12v. Now looking on possibility to read and clear codes thru OBD2. Maby that’s the only issue but I don’t have that tool , maby I could rent it out than ? So here I’m now . Please give me little push to finish it up . Thank you . Have a great day to all 🙂🙌

 

Anybody tried Jbl bass pro on your Mazda ?

 

check fuses, I'm posting Mazda 3 wiring diagram but I think CX-50 uses the same Panasonic infotainment system. Clearly your display is not getting any power because of DAA alert, the camera inside panel monitoring your face is not working. Verify 12V Power Control Out when you push Volume Control, If Power Out driver is blown you would need to go to dealer to replace and program CMU.
