Have you done the DSP settings? There’s so much in there I can’t figure it out. Why can’t it just be simple bass, treble, and mid 😂

Yeah, as suggested by @Dave_R check the wiring you have and make sure you order the correct MOST box. I initially ordered one from eBay, but it had the wrong connections. You can post some pictures here and I may be able to help, as I did a lot of research to get mine working. I know how frustrating it is when not all the speakers are working. Also, have a look under the passenger seat to make sure all the wires for the amp are still there and haven’t been cut. I was lucky — they had only used an amp bypass cable, so everything was still there.

Just wanted to give an update in case anyone runs into the same problem, and also say thanks for all the help on here. I had everything wired up but wasn’t getting any sound. The MOST box had a flashing green light, which indicates the MOST network wasn’t complete. After digging through a few threads, I found someone mentioning that if the roof monitor isn’t working, the network won’t complete. They suggested bridging the wires, so I tried that — and as soon as I bridged them, the sound came on and everything worked. Hope this helps someone else. 👍

@lawrence do you still have the orginal unit im interested in purchasing as it looks like the same connections I have. Or if anyone has the same one

I’ve connected a MOST system to an Android head unit. The system powers on correctly and the Android screen turns on. I have connected the RCA front left and right outputs. The MOST interface shows both a red and green light, so it appears to be powered and active. However, I’m getting no audio output at all. I’ve checked volume, balance, and fader settings on the Android unit and nothing is muted. All connections seem secure. Has anyone experienced this before or can point me in the right direction on what to check next (settings, wiring, coding, etc.)? Any help would be appreciated.

Thanks for the info. I’ll wait for the wires to arrive and see if it works. I’m not really fussed about the rear screen — I just want all the speakers to work. Currently, the middle speaker at the front is working, two at the rear, and the subwoofer 😂 It still sounds really good. Can’t wait to hear it with all 18!

I bought the car with an Android head unit already installed. It has the factory 18-speaker system, but it looks like the previous installer bypassed the amplifier. I’ve ordered the MOST system from AliExpress and am eagerly waiting for it to arrive, hoping it will allow the speakers to work properly again. In the meantime, I’m trying to figure out how to get the roof monitor working. I’ve seen some mentions of pins 1 and 2, but I’m not sure exactly where they are, what they connect to, or what needs to be done overall. If anyone can shed some light on this or point me in the right direction, I’d really appreciate it. Thanks in advance for any help.
