Stereo amplifier
I have a 1988 740 with a Blaunpunkt Toronto SQR 48 head unit. I am only getting sound from the front speakers, and even then only at an audible level from one of them. It is my intention to replace the head unit but despite my crawling around under the dash I have been unable to locate the external amplifier. The head unit will be replaced anyway, but I want to at least check the wiring first.
There are remnants of a car phone installation that used its own speaker, and something that looked a bit like an old computer vga connector not attached to anything that I presume is related to the phone rather than the stereo but I cannot see an amp. Does it even have one? Am I looking in the wrong place?
