86 325 BMW - Want a new stereo with CD player - but not aftermark
My husband's '86 bmw 325 has the WORST stereo system - speakers are awful. I would love to replace the system with something that has more than a tape deck. He hates the aftermarket look though. Is there anything out there that I could buy and have installed that would look factory made?

If it was me i,d replace the original head unit with an alpine they came standard in most early bmw,s and maybe and an ipod to the aux input of the stereo.
the speakers are 5,25 inches and there behind the flimsy front kickpanels you can either just swap them for something more powerful i,l recomend genesis or rainbow for a big difference in sound especially if there a mid and tweeter combination that your buying , if not just a good coaxial set will do but stay away from the kenwoods they lack in midbass !

Go to a Salvage Yard or contact Car-parts.com which is a collection of online parts salvagers. There were optional radios which had this feature and also a 6 CD stack for the trunk.
The biggest thing would be to make sure the wiring is compatible if going to a trunk mount. But a dash mount single radio/CD is probably the cheapest way and I would think the speaker wires should be compatible.
The manufactuers used a 4 pin lock system in the front dash facing of the radio. You can get the simple release pin barbs at Walmart or most autoparts places. Just insert the barb pin stems into the 4 square holes and press and the radio should come out.
If you have volume but cannot control it, this is a common problem. The volume is optical so it may just have dust in it, but I have had zero luck cleaning them. The only solution I know is to replace the whole head unit.
If you have an HK factory stereo with no volume at all, and the four channels went out one at a time, the amp in the trunk has failed. Another common problem. The amp is on the driver side above the wheel well. You have to remove the driver side rear deck speaker to get the trunk lining off without tearing it. The screws that hold in the speaker are beneath the speaker grill in the rear deck. Good luck getting a 15-year-old speaker grill up without breaking the snaps. Slide a putty knive in from the sides to try to release them, but they will break anyway.
If the amp has failed, you can just bypass the amp but you will have no subs or tweeters. I did that while looking for a good deal on a junkyard amp. You can buy a new HK amp from BMW but they are prohibitively expensive. You could buy an alternate brand amp and add crossover circuits to power the subs and tweeters if you are really handy with electronics.
If you have an HK system in your BMW and you replace the head unit, use the antenna power wire from the new stereo as the 'on' signal for your HK amp in the trunk. Your FM may not work quite as well because the BMW head unit communicates with the antenna amplifier. Also, if you have a BMW CD changer in your trunk, no other head unit will communicate with that other than the original BMW head unit.
Other than the CD changer and the antenna amplifier, the wiring adapter that you can get from Crutchfield or from Amazon will make the stereo head unit replacement plug-and-play.
You may need a special five-sided wrench to get the old stereo out. You can buy that wrench on line if you can't force some other tool into those two cap screws that hold the stereo in.
I hope this would help you:

Try radio shack, or stereo sales/installation place for ready to go plug adapter. For a few bucks, it saves headaches, and butchering the wiring in case you want to re-install old one later when trading in or selling the car.
