1991 BMW 325i Q&A
1991 BMW 325i Question: weird sound through speakers when radio is turned on.
Hi, this only happens when the radio is on (ofcourse). Any action which utilizes current, such as stepping on the break which means the break light turns on, using a turn signal,turning on wipers gives me an audible "poof" like sound to eminate from the rear speakers. Clearly it must be the sound system (it is the original one) but I don't know where to start. Has anyone experienced this before and do you have any suggestions on where to start. I don't want to install a new radio since, once it's on, there is no problem with the sound... Thanks in advance! - girlgeek2
Check for RF interference. Any new bulbs been replaced recently? It's not the radio but the wiring having poor insulation somewhere. Check the basics... - Hal...
