Code7rpd, much appreciated !
Used to use a battery to test wiring polarity back in the 80's when I did a lot of installation but I didn't want to have to take off the covers to label each wire. Thank you again.
In reading so many previous threads I was expecting 5 channels. Can anyone confirm the factory Bose speakers have x-over components at each speaker and can handle high or low passed signals from a replacement amp?
Excited to replace this wonky interface.

Loi at Euromotorspeed hooked me up with both the HU & amp harness for my 997.1 With Bose vehicle. Great guy who seemed to have a decent amount of experience with 997 models.

Great writeup! I think I'm going to go this route in mine (997.1 w/bose)...some questions for you:
- Does the screen dim based on the vehicle's dimmer?
- Does it dim sufficiently at night?
- Do you use hands free calling?
- Where did you wire the microphone?
- Call quality good?

2. Yes, no bright LEDs or other gimmicks
3. Yes
4. Mounted it on top of the steering wheel pillar just behind the wheel
5. Not bad for a single microphone. It works OK for what it is, but will never be as good as the multi mic stock system.

FYI for anyone who may be interested or confused.... the 997.1 is totally different animal from the 997.2. So be careful. The 997.2 (PCM 3) is a 5.1 surround system where the head unit talks a proprietary protocol to the processors/amp located under the passenger seat. This system and protocol is very different than the 997.1. Further, the 997.2 was sold with a premium vs base stereo option and the head unit in the dash, is configurable by the dealer to be either.... this activates/deactivates the pins/optical connections in the rear of the unit. Said another way, if you have a 997.2, your are in for careful analysis.

Any chance someone has a picture of the amp end of the Bose subwoofer wiring and guidance as to where it would come into the carpet opening under the passenger seat (997.2 coupe)? PO replaced the headunit and amp but never reconnected the sub. I'm trying to locate the wiring so I can reconnect it...

Number of RCA cables
Nice write-up! I know this has been a few years of this post. I am interested in doing the same project on my 08 Boxster. I see at least two RCA cables in the pic. Can you share more information on what they are connected for?
