I've been looking into bluetooth amplifiers and speaker boxes - I don't want to cut holes in my rear deck. I would bluetooth directly from my phone to the amp. I stumbled across this all in one solution. Yeah not audiophile quality, a little expensive but I'll bet it puts out decent sound. I'd put it in the middle of my rear deck, no holes :)

How would you anchor it without drilling holes in the shelf to prevent it from becoming a ballistic missle? It would sound just as good on the passenger seat or footwell, I find chasing audiophile sound in a coupe to be a time and $$$ waster. Basic tunes is good enough, the rest is engine music :)

I had in mind to go ahead and drill a few small holes. Just avoiding the bigger holes for speakers. Yeah, not chasing audiophile :)
 
A couple of comments on sound in cars. First, you need to consider the sound deadening in your car as part of the sound system. If you don't take steps to diminish road noise, it will drown out your music. (And, unfortunately, glass transmits noise well, so while the large greenhouses on our cars are pretty, they make diminishing outside noise difficult).

A second consideration is how we perceive sound. We are not very good at identifying the location of low frequency sounds, which is why subwoofers can be located below or behind us. We are, however, good at identifying the location of higher frequency sounds - like voices - and here having speakers at ear level, or close to ear level, makes a big difference. Alas, with our cars, there are no unobtrusive locations that would put tweeters close to our ears.
 
I saw on an old thread somewhere a guy replaced the ashtrays in the door with some tweeters and really made it look OEM.

Interesting thread, thanks for posting! I gave up along time ago trying to get a decent sounding system into my E9. First, my hatshelf is untouched and I wanted to keep that look before I went ahead and resto moded the rest of my car. I've also been told my car has had most of the interior soundproofing removed by the previous owner and the biggest factor is the Coupeking exhaust I added in 2011. All totalled, not a great basis for a good sound system. And, like Ohmes, I do rather like the powertrain sound tracks of our cars. Howeever, I was investigating this kind of bluetooth powered speaker system for my other classic -- my 1987 Mercedes-Benz 190E 2.3 16V. It has the wrong head unit, some screwy wiring going to crappy "upgraded" speakers installed by the previous owner. I'm ripping everything out except for the original look head unit and was contemplaing a small powered bluetooth speaker installed somewhere in the rear...
 
My coupe had never had aftermarket speakers installed, so the hat shelf, kick panels and rear seat forward panel are all un-cut. When I had the interior apart I did install sound deadening in the front door cavities, rear window cavities and throughout the floors as well as under and behind the rear seat.

I purchased a retro-sound radio and added a decal to the face plate to further hide the fact that the radio is modern. I upgraded the speakers in the dash and added custom auto sound undercover II speakers that, for the most part, fit under the front seats from behind. I ran the wires to the front seat cavity while the interior was apart. In the picture below you can just see the back end sticking out from under the front seat.

It would not be practical to keep these if we had another person riding in the rear seat, but that doesn't happen often and the speakers are easily removed and the wires tucked back under the front seat cavity. I enjoy having some music to distract me when on the highway.

It was @rsporsche who did it. See this thread. I think he did a great job.

Best interior color to pair with Arktisblau?

Erik, i put tweeters in my ashtrays and put perf metal (black) where the vinyl was. it looks great. this is not mine, but it looks exactly the same. i am going to put tweeters in my rear side panels (window motor access plug).
