1) Was there any programming/wiring to be done or was it directly plug and play?

2) Was there any change in sound or performance?

3) Was there an improvement in sound and performance?

Thanks

 

this is tuning, and all tuning are crazy...

next thing - most my installations are cayennes, and there bose system dramatically improve sound quality compared to stock non-bose, so some add 3000$ to install bose plus to pcm3... and more for tv, for rearview camera

nobody adopt pcm3 to old optical bose since it just not play in new system, amp is also new, and sounds better than old version

used burmester amp costs ~same as used bose amp. speakers wasnt available, buying new for used car - sure crazy


well, it was just p&p test, but for normal performance wiring needs to be changed - for example front become rear, rear become front.. so noticeable sound improvement will be after correction, and changing speakers to burmester... well known that burmester sounds much better than bose... coding on old car is not possible, but amp is seen by piwis as bose with some exeptions...

 

Has anyone actually looked behind the installed Bose unit in our USA cars? Is there any access actually there other than the amp outputs and the communications in/outs?

I remember reading a long time ago that there is just no access to line-level, pre-am outs. The sockets and or wires are just not exposed.

Thanks for sharing some of your experience. Seems that in Russia people will pay some insane money for factory hardware! Not like this is even an OEM upgrade, because you are upgrading older cars to PCM 3.

When you say no point in adopting optical Bose to PCM3 - is that because the PCM3 is no longer an optical interface? That's interesting. As I've said, I get plenty of power from the PCM3 Bose amp, so don't have much interest in changing it. Not sure if a Burmester Porsche amp would have significant benefit over a good JLAudio amp or comparable, at a fraction of the cost.

Thanks for sharing the experiences.

 

no-no, I've told about pcm2.1 bose amp, pcm3 needs own amp, it is optical bose too but pcm3 version.

about insane... not all unfortunately in fact most of owners when choosing from "factory diagnosicable expensive" and "chinese cheap crap" choose third - not to do anything

 

Here's a pic of the back of the PCM3 with Bose. Notice there are some empty connector spots.

 

Presume one would simply need a non-Bose oem wiring harness?

 

unable to buy this. only self-made harness.

 

Then you can get the plugs? Without the plugs or harness that would be a real nightmare.

 

as i understand it from other forums, this is the only off the shelf solution that enables you to go back to the OEM headunit at a later stage:

of course plugs and pins are available, 3B7035447 plug and N90684505 pins
version of result on photo, not mine but sure gives the idea.

 

Or you could buy the Euro Motorsports kit that replaces the Bose amp and includes connectors so you do not have to cut into your factory harness at all.

New head unit and amp could both be replaced without any permanent modifications. Easy to go back to stock.

I just ordered one.

 

like this one? and how much they charges for it? it not replaces amp - it omit it. different thing.

 

Hmm, neither of those harnesses look like they would plug in to the back of my PCM3. Something isn't right.

Edit - I see a spot where another 8-pin connector could go on the PCM but the pins are missing. This is on a PCM3 w/ Bose, US version. Have a feeling we are missing the circuitry for the pre-outs.

 

what pins are missing, what you talking about?
