The car is a 2004, Boxster S - 986, with "Bose High End Sound Package" option. This Bose system has the CDR23 head unit and an amp in the front trunk. There are left and right speakers in the dash, the doors and in the rear mounted speaker box. The rear mounted speaker box has two small speakers on the left and right and a large port in the center. I am a persistent person, but I am finally having to reach out for help. After several months of off and on searching for information, I finally decided to pull the trigger and replace the head unit in the Boxster. From reading an unbelievable number of posts on this and other forums, I was convinced that the best course of action was to circumvent the MOST system and replace the head unit and amp together. Contrary to most advice, I plan to keep the original speakers (at least initially). Wiring is the challenge. My thoughts were that I would replace the pre-amp wiring with new since that is where the MOST system is in play so this was a no brainer. I purchased a wiring harness from Crutchfield to keep the original harness intact. While it did allow me to keep the harness, it only mated to 3 wires (and Crutchfield had two of those wired incorrectly). Luckily searching this forum and using my multimeter, I was able to figure out what was needed for the head unit. Pulling the pre-amp wiring from the new head to the front trunk turned out to be easier than I was expecting and wiring the amp for power is a breeze since it is almost on top of the battery. Now, speakers. I thought this was overly complicated from the post and some extensive DIY posts that I read, but I pushed on. I hunted for days on end to find a wiring diagram that matched what I was finding in person and have still not found it; I have looked at numerous ones, but none are actually like mine. I have come to appreciate that Porsche has many ways to wire these things and it is almost like everyone is unique. Not having a wiring diagram that worked, it was pretty easy to separate the speaker wires from the others on the wiring harness that connected to the original amplifier. My plan was simple, put an audio source on each of these and map where sound comes out. The first unusual thing that I encountered was that there were only 5 speaker wiring pairs. I expected 6. As it turned out, two pair mated to the left / right dash speakers; two pair mated to the door subs; and the last pair drove both speakers behind the seats. This is odd and made me wonder if there is actually a subwoofer back there, especially with the large center mounted port and the fact that the visible speakers are very small. Has anyone else dealt with this configuration? Does anyone have a wiring diagram that matches this? The amp is marked as a Bose 996.645.333.05. I have searched for information without any luck. The pins are such that it appears to be a 5 way amp, but I would typically think that the single would drive a sub, but all the information that I have seen says that the door speakers are actually subs. My thoughts right now are to continue to treat the door speakers as subs. I am going to wire them in serial to get the impedance up. My understanding is that they are 2 ohms individually. I will drive the two dash speakers normally and then drive the rear speakers as a mono channel. Any experience and/or advice out there? Thanks

I have a 2003 Boxster with the CDR23 radio and external amplifier mounted in the front trunk. There are two multi-pin connectors, a fiber optic connector and an antenna connector on the rear of the head unit. The display on the head unit in the car seems to be fine as the display appears to be working as it should. The problem is no sound out of any speakers. The problem was intermittent for quite a while as sometimes when I started the car I would have sound from the speakers and other times no sound. Sometimes I would be driving and the sound would suddenly just quit. Now there is no sound at all, but the head unit display still appears to be working ok. Does anyone have any suggestions as to what might be the problem? -
Hi Folks I don't know if this has been covered, but I recently bought a 996 C4s it has the bose system and a CDR23, it has a Dice 30pin iPod connector which as we know does not fit the lightning style connector, tried various adapters that did not work, so I ordered a bluetooth adapter which plugs onto the 30pin connector LAYEN i-Dock 4.0, cost £24 approx. Connection to the phone is easy and it worked without any problem in fact I would say that the sound quality is better as you can control the input to the stereo from the volume control of the phone. Only negative, which in my opinion is that the normal text you would see on your stereo just says empty station, but I can live with that. Positives, keeps the car original, I can hide the cable altogether the bluetooth adapter is very small and the car now looks original, I can use any phone that has bluetooth to stream my music. Don't have to put a new interface or stereo system into the car. Anyway this is day 1 will add to this thread once I have experimented a little more, incoming phone call etc. All the best Martin

I replced the CDR23 with Seicane Android HU. It comes with Canbus adapter and I purchaed MOST adapter with it to make it work with factory Bose amp. The unit powers up fine, but the MOST adapter needs to have power to work. Any suggestion where can I connect the three wires listed in the pic to? I assume the main socket that was connected to the CDR23 has power, but don’t know which wire is which. How easy would it be to get power from lighter adapter aux? I am planning to replace that lighter adapter with USB port for the HU as well. Thanks

Hi there ive just returned to porsche and got myself a 2002 c4s, love everything about it apart from im struggling to find out how i can connect a iphone / ipod. From what i understand the cdr23 is a most bus stereo and it only has very expensive ways of adding a aux in. But i also dont think the most bus system came into the 996 untill 2003, so im a bit confused!? I have a amp in the front, but no disc changer, i also dont think i have bose as theres no badges on the door speaker grills, neither is there a rear speaker box. If u can help at all id be very grateful, it think i have a stereo fitted that wasnt ment to be fitted till 12 months later :/ Forgot to say it has the cdr23 stereo fitted
