From what I can tell, the car may have the premium sound system it has the front kick panel speakers, and I believe it also has the wiring for tweeters, although I could be mistaken.
I've been trying to locate the amplifier. I checked the trunk and couldn't find one.

Does anyone know if there's a wiring diagram specifically for cars with the in-dash fader knob, or can anyone confirm whether these cars actually have a separate amplifier and where it's located?

I don't need anything too fancy. Reasonable sounding radio, bluetooth hands free calling would be a plus.

I'm a durable goods purchaser. Don't mind spending a bit more to get something better that will last longer. Searching on line, I'm confused as heck! There are so many options out there. I like the look of the BLAUPUNKT units but they seem very expensive for what they are. But of course, I'm no audio expert.

I appreciate any insight!]]> tomstin https://www.r3vlimited.com/board/forum/e30-technical-forums/car-audio-electronics/10164464-help-me-pick-a-new-head-unit https://www.r3vlimited.com/board/forum/e30-technical-forums/car-audio-electronics/10163719-cm5908-code-help Tue, 07 Jul 2026 06:05:25 GMT
