Absolutely no audio in car!
OK bit of a story here but a quick synopsis of my issue is;
Installed a Vibe amplifier to my F30 335D under seat subwoofers and forgot to unplug one from the original speaker wiring loom. I know have absolutely NO audio output through any speaker. No DAB, no BT audio, no USB audio, no door chimes, PDC etc..... Now for some details; The car is a base stereo unit – amplification comes from the HU which is a NBT EVO ID4 4 door card speakers and 2 under seat subs. I originally installed the VIBE 65.4 Amplifier (harness for original ISO loom) to boost the door speakers which worked fine and was a decent upgrade. Added two Audio Fischer Co-Axial speakers to the front doors to bring some much needed treble, again system was working fine. Now things started going wrong.... I then thought the lower end BASS felt a bit lacking so decided to get the Vibe 400.1 sub amp for the under seats. I soldered 2 new speaker cables to each sub and hooked them up to the 400.1 amp. What I failed to do was unplug the original wiring loom from both subs. I these come from the HU to the subs and then up to the door card speakers. I unplugged the loom from the drivers side sub but not the passenger side sub. I then foolishly powered on the amp and I now have absolutely no audio whatsoever!! There was no pops or bangs when the audio went. Things I have checked so far; Firstly I returned the car to stock, removing both amps and plugging in original connections as before I started anything., Every fuse in the boot and engine fuse box. Checked visually and with a multimeter. I actually found a blown 20A but this was related to the front cigarette socket. Every door speaker with a multimeter and they give around 8 ohms replaced the HU and no difference unplugged the car battery and left overnight (12 hours). Only things left I can think that might be damaged is the wiring somewhere or something to do with the coding of the car? I have included screenshots of a recent ISTA readout that shows issues with the ASD unit. I have no idea if that would affect current audio. Any help that results in the remedy of this problem will be much appreciated. I am currently driving with a Bluetooth speaker to keep my sanity. [ATTACH][ATTACH] [/ATTACH][/ATTACH] |
