I'm trying to install an OEM BMW rear soundboard set for my E30 Convertible, but unfortunately I don't have the installation instructions.

I'm mainly trying to figure out how the soundboards are secured.

The attached photo shows a front mounting screw next to the pull handle, but my soundboards don't seem to have anything there for the screw to attach to.

Were these soundboards originally supplied with an additional mounting bracket or support that bolts to the panel? If so, could someone post a photo of it or explain how it is mounted?

I've also attached a photo of the back side of the soundboards.

If anyone has the original BMW installation manual or detailed photos of the mounting hardware, I'd really appreciate your help.



​

Thanks in advance!

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
