do you get AM reception? I suspect I do not because the diversity antenna is no longer connected. I think there may be a double fakra connector to single antenna adapter.

I'm not sure about AM reception because I don't listen to the radio often, and when I do it's always a FM station. I do get phenomenal FM reception. The antenna adapter part(s) you are referencing are:
1) Metra 40-EU10
2) Metra 40-EU20
I purchased both prior to my installation just to be on the safe side, but ended up only needing the 40-EU10.
Yes I used the Metra 40-EU10 as was suggested in 2 other posts. The EU20 has a female end so wouldn't be applicable. Found a twin fakra on eBay. I use AM on occasion for news and sports.

Reason: added words
So, after I replaced the HU, everything was working fine. There must have been a power draw and the battery died after leaving the CTT parked for 4 days in cold weather. I recharged the battery and the HU is working fine, but the speakers are cutting out, similar to the issue I was having before replacing the PCM 2.1. I thought it was the PCM's fault, but apparently, it's something else. Any ideas?

1. If always the same speakers cutting out, then it could be the wiring at the speakers or at the amp.
2. If it varies which speakers are cutting out, then I suspect the factory amplifier.
3. If ALL the speakers cut out, then I would say the problem is definitely at the amplifier. However, in this scenario, it is very possible that the power or ground is just lose, which should be an easy check and fix.
When I do my upgrade, I am going to avoid number two or three, because in addition to replacing the factory head unit with an Android unit, I am replacing the amp with an Alpine amplifier with built in DSP. https://www.alpine.co.uk/p/Products/...ew/PDP-E800DSP
I am going to try using the factory speakers to see how they sound first. Because of the sizes and configuration, I will try the easy way first. If I don't like the sound, then I will replace the speakers as well.
I changed out the amplifier and this didn't help. I will now check the connections to all 14 speakers to look for a short. Apparently, these speakers will all cut out even if there is a short on just one component. I assume that includes the DVD Sat-Nav player under the passenger seat as well. I did have water ingress on the floorboards recently, which I remedied by pulling the seats and carpets out and drying everything as well as clearing the drain holes under the wheel cowlings. Perhaps there is residual moisture in the DVD player? Does anyone have the wiring diagram for the PCM 2.1 sound system?

From the wiring diagrams I have seen, the speakers aren't wired in series, so a problem with one speaker should not take out all of them. Problem at the CD or DVD/Nav unit? Possible, but the wiring into or out of the amplifier and/or head unit sounds like a more likely scenario. JMHO.
If you have a power draw strong enough to kill the battery in 4 days, find that first. There are a number of well documented methods around on locating power draws. Maybe it's the same as what's causing your audio issues.
Even if one of your speakers is shorted it should not draw power when the car is off, as the amp should be off.
The RCA cables from the Scosche LPPE15 are labeled rear L and R. That's where I plugged them in on the Sony, but now I have no sound from the phone because it only uses the front speakers, apparently. I guess I should switch the RCA's to the front?
On the sony, there's an option to have the phone use the front, rear or both. I told it to use rear.
Graduation on your successful endeavour. I have a 2006 Porsche CayenneS with only the radio system of Bose [ without any GPS, DVD, blue tooth....etc] I intend to upgrade it by installing an aftermarket Android head unit. But, many suppliers say I need to buy the Bose optic fiber decoder in order to get the audio. Others say I also need the Can Bus decoder as well. I am new and confused. Just wonder anyone can give an accurate and proper advice!
Moreover, I wonder the wirings and cables in the Cayenne are adequate to cope with the installation of an Android unit! Much appreciated for the assistance.
