Catfish 0 Report post Posted September 27, 2022 Hello guys. I somewhat recently purchases a 2005 BMW E46 320CI. Since it's been in my ownership, I've only had one singular speaker function, and I am getting over it. The only speaker that works currently is my passenger door speaker, the tweeter in the passenger door does not. I've tried moving the functioning speaker around to other places to try and figure out if it's my wiring that's gone, or something else. By putting my only functioning speaker into the two rear shelf positions it did not play any sounds at all. I've done some googling and I am really struggling to figure out what sort of HiFi package I have in my car, as it seems to have the base range speakers, but with a SatNav head unit. I found a VIN decoder, and this is the codes that come up for my car; 550 - On-board Computer 602 - On-board Monitor with TV 644 - Prep for Mob. Ph. Bluet. Interf. 650 - CD Player 692 - CD Changer IBUS Preparation The battery and all the computers for the audio is in the boot of the car, and after looking around I found I have a BM53 module in there. Radio functions as it should, head unit (while it has burned out spots) functions as it should, and I am quickly running out of ways to troubleshoot. I found a HK amp in my local wreckers and picked that up dirt cheap, but my car doesn't appear to have any wiring for an amplifier ready in the boot. Anyone have any ideas, or will I have to replace the whole system completely? I'm happy to supply photos or videos if that helps anything. Thanks Quote Share this post Link to post Share on other sites
