Navigation & Audio R56 speaker replacement how-to

and with that last post this thread has achieved legendary status.
everything anyone could want to know about upgrading their sound system has been explained (if you don't count changing the headunit)
The inputs to the amp are also the speaker leads in the non-HiFi system.
The only thing left is for some people to show some examples of subwoofer installs.

NOTES/DISCLAIMER:
!!! THIS IS A WORK IN PROGRESS !!!
!!! THIS IS FOR THE HIFI SYSTEM, AND LABELS THE AMP CONNECTOR(S) IN THE REAR OF THE CAR !!!
!!! PLAY WITH THIS AT YOUR OWN RISK! I AM NOT RESPONSIBLE IF YOU SCREW UP YOUR CAR !!!
Last Update: 19 Jun 07 (Pin 10 amp connector).
What I ultimately intend to do is replace the stock amp and speakers, but use as much of the factory harness and locations as possible. I figure I can use the speaker level inputs that run to the amp, and either convert them to RCA or get an amp with speaker level inputs. Then, I'll put the crossovers in the rear quarter as well, and run the factory speaker wires from there.
I still need a little help, because the car uses both CAN and MOST (two new busses). There shouldn't be any real impact digging into the system at the amp, unless your car has navigation, bluetooth, etc... I have no idea at that point.
Here's oPossum's link to the connector pinout The pinout is important, because in some cases (like the rear woofers) the same color wire is used more than once.
If you don't want to cut the wires on the connector, you can pick up a tool at many PC shops to remove them from the connector... like THIS or THIS

Solid brown is always ground on BMW, VW, Audi, etc...
Yes, it is CAN bus. The old H/K sytem used I-Bus to talk to the amp. If it didn't find the amp it would disable the H/K specific features. The R56 may do the same thing.
Pin 13 on the radio is switched power for amp turn on.
Amp power goes through the JBE. Looks like a dedicated circuit. Cars with the new engine auto start/stop system power the amp from the DC/DC converter. That converter must be HUGE!

The radio connector follows a standard pinout. Pin 13 is for the power antenna.

What's confusing me is that "The amplifier has a separate power supply. The amplifier is switched on by the RAD_ON signal from the ASK (> 8 V = ON / < 6 V = OFF)."

It does go to pin 10 of the amp. I missed that page. Here it is
The CAN bus is usually terminated in the harness (120 ohm resistor at each end), rather than in any module. Disconnecting the amp shouldn't cause the bus to become unstable. If the radio doesn't like it, maybe it could be recoded by the dealer.
Why is that confusing?

So while on the topic of trying to figure out the proper pins for amps... I don't have the Hi-Fi system seeing as I figured I would end up replacing most of the system eventually. I know that mikethemini does full system replacements over the pond, but I am trying to figure out how to do the same thing to my Mini. I've got it narrowed down to an amp in the place of the DSC foam block and speakers in the doors using the stock wires (not desired, but the only real way to do it). My only question is how to take off enough of the center console to get to the back side of the radio to tap into the connector or use one of Mike's special connectors? I know it is pretty involved, but that seems to be the only method for for getting a signal on the stock non-HiFi system correct? Any recommendations on where to look for removing the dash?
Thanks.
Thanks.

MM,
I am looking to replace my speakers but i would like a little more endorsement from you. The HiFi setup sounds good to me. the problem is that i like loud music. And i like to drive with the roof open. I find that i need to keep the volume down because of the distortion in the higher frequencies. low frequency distortion is probably there as well but i cant detect it due to the wind noise.
My goal in replacing the speakers would be volume. Will the focals do that for me? i will be using the stock amp and capacitor on the tweeter as you had first done before the new amp.
eventually, i amy also tear apart the back so that i can get to the amp and i will disconnect the rear tweeter wires. (to keep the soundstage forward). it would be interesting to throw in some 6x9 midbass drivers....
thanks
(still waiting for skuzzy to give an opinion of the focals from the stock HiFi amp!)

You'll be happy with the front focals in place of the stock speakers. They go alot louder before distorting although there is distortion at the really high end (relative to stock) due to the amp running out of juice. The front focals will give more midbass by themselves than the complete hi-fi system including the 6x9's in the back.
The last I heard from skuzzy is that it sems to be monsoon season where he lives and hasn't stopped raining long enough for him to install them.
Although I have the focal 6x9s in the back running off the stock amp there may be a better choice since there are no highs going to the 6x9s. I read somewhere where someone used MDF to make a plate to cover the 6x9 hole and made a cutout for a 6" midbass driver. You might be able to do the same thing for a 7" (if you can find one). Look for one with a high db per watt level since the amp only pushs 40 watts to them (and distorts at that wattage).
If I didn't bridge my 4 channel amp to the front focals I would have had the amp powering the 6x9s also and I'm sure they'd rock a LOT more than they do. I think I like it more with twice the power going up front though.
The focals really shine with 100w+ per channel going to them.

thank you. I am also considering the less expensive JL audio 3 way set. and these http://www.theautophile.com/products...sNavFrame.html
for the rear. (i really wont be getting these due to price, availability and my fear of tearing apart the rear to get to them....

kookmyers - Since price seems to be somewhat of an issue for you; get into the tone menu and try turning the bass down a bit (-1 or 2), and fading a little to the rear (3 or 4). I think you'll be surprised how loud the HiFi can get (and still maintain decent punch). Bass takes a lot of wattage, but the highs are the first to really show the amp is clipping.
Adding better speakers will do a little for clarity, but not really volume. The HiFi amp still only makes so much power. If volume is what you're after (and the settings above don't work for you); you might consider upgrading the amp first. It's a whole lot harder to blow a mediocre speaker with a powerful amp than it is to blow a good speaker with a crappy amp.
Rule of thumb is:
Bigger amp if you want it loud,
Better speakers if you want it clear,
Both if you want it loud and clear.
