I just happened to find another post about that and when I weighted down the console armrest AND disconnected the brown/blue wire.

Mine broke a long time ago and I replaced with the upgraded metal hinge.

thanks, i tried disconnecting the brown/blue from the spade connector which was wired to the radio's ground.

One set is then spliced into the after market speaker wire, and then the other set goes into a cross over, which then powers the front speaker (tweeter and woofer pair).

Well the last piece of parrot was to remove the aux input from back of stereo but can't get it out (don't have the pioneer key, so using credit card strips), but this is where we are now haha.

And yes there being two of the same wire is really odd (though are they just one continuous wire that is simply spliced in middle using female connector?).

Using some strips of plastic I was able to slide them in there and release the tabs, and then pull the unit out from the rear by removing the AC controls.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I'm trying to remove the Parrot system that came with this car. The parrot has two sets of speaker wires that run to each front speaker (two + and two - to each L and R). One set is then spliced into the after market speaker wire, and then the other set goes into a cross over, which then powers the front speaker (tweeter and woofer pair).
I was following the parrot's pair of wires that ran up to where the relays are and where the crossover is hung. I was fiddling with them and the horn honked twice.
What would cause that? I was lightly pulling on them to hear where they went. But nothing dramatic.
I've also get a horn honk after locking the doors and wondering if they could be related.
Here's the crossover and the spliced wires that go in to the Woofer +\- and then the speaker out for Tweet and Woofer +\-. I don't know if that has anything to do with it.
I've already removed the splice and parrot. I don't think the Parrot would cause a honk though.
I don't know why there would be an interaction between the speaker wires and the horn or alarm but the double honk when locking the car is from a problem such as an opwn door or trunk.
Sounds like the original radio alarm wire is grounding out. It should be a lone blue/brown wire with a female connector. When it's pulled off the isolated section of the factory radio, it grounds out and causes the alarm honk. Common on 996 cars with the CDR-220.
My recommendation is to locate and cut the original connector off the brown/blue wire and tape the end of the wire to prevent grounding out.
^^ This. Porsche originally wired the factory radio unit with a ground wire to the unit. This was for protection/radio theft protection...and wired into the brains of the immobilizer/theft detection system.
Well the last piece of parrot was to remove the aux input from back of stereo but can't get it out (don't have the pioneer key, so using credit card strips), but this is where we are now haha. Noticed a ton of the foam from vents inside this cavity, the seal to the front center vents is not so good, most the air just blowing straight into the back of the AC controls.
So can get to ground wire to check it.
There usually aren't "keys" to remove aftermarket stereos. It's more likely to have a "cage" around it with tabs that are bent tightly against the frame to hold it in place. You'll probably need to remove the entire horseshoe to get the headunit out.
Is this the blue/brown (see pic below)? There are two of them that come from the factory harness as part of the defrost, "key", and rear wiper buttons. They are joined into a female connector that is then spliced into a black wire that goes into the head unit, which connects to the large brown wire as part of factory wires.
I don't know how those would be affected by my fiddling on the far left side of dash and cause a honk? But could they be related to the honk when locking the door?
The Pioneers have two keys that slide into small slots on the left and right and release a little latch. They have a tab on them to then allow you to pull the stereo out. Using some strips of plastic I was able to slide them in there and release the tabs, and then pull the unit out from the rear by removing the AC controls.
Normally, it's a single conduction brown/blue line. I don't ever remember seeing a dual conduction version.
Look at this schematic. You'll see the "RADIO WITH ALARM CONTACT" section on the right. That's showing a single "BR/BL" line. That's the one you want.
Well parot is now gone. Found XM buried behind passenger footwell and removed that too. Left all the XM wiring in place in case change mind ever.
Left remote wiring to head unit and amp.
Left hot wire splices with caps and tape in case ever need more accessories.
Left the two brown/blue wires from non-stereo factory harness to female to ground of head unit harness. (this is the part i'm confused by)
Jiggled everything under relays and no horn. But again I don't really know if any of this was related.
Still get single honk after locking car. Two amber flashes then a single honk... Again not sure if related to double honk from futzing with wiring.
I replied to soon above. And yes there being two of the same wire is really odd (though are they just one continuous wire that is simply spliced in middle using female connector?). But they are coming from the factory bundled harness and were part of the bundle that feeds the side panel switches. But then the male single wire was wired to the radio ground.
So am i supposed to just disconnect them ? What does having them grounded with the radio cause to happen?
No, I wouldn't discount them.
IMHO, it's probably a revised way of doing the same thing. Examine D83 on the schematic. You notice that when it's "happy" the circuit is OPEN. When it's closed, it's unhappy.
If it were me, I'd cut both wires about 2 inches back from the connector and tape BOTH ends of the BR/BL wires separate from each other and that should make the car "happy" again. jmo Test and report back.
Here's a good picture of the single conductor BR/BL alarm wire. It usually routes from the driver side (US cars).
I know it seems odd, but to prevent an alarm honk, you must clip off the L shape connector and tape the end to prevent grounding out against any metal surface.
thanks, i tried disconnecting the brown/blue from the spade connector which was wired to the radio's ground. But still get a single honk when locking the door.
It looks like it originally was wired to the case of the radio, which i assume was grounded. So shouldn't it also be grounded to the common ground?
Im not sure if i should leave them disconnected or put them back together now.
Actually found it!
it was a double problem. That brown blue wiring was part of it but also it was my center armrest console does not close properly because the rear hinge broke. I just happened to find another post about that and when I weighted down the console armrest AND disconnected the brown/blue wire. No more beep!
I tested each independently and both attributed to the honk. So glad to have that done!
Still don't know why it honked at me with the door open while i fiddled with front left speaker wiring....
Silly question I am sure, but the center storage box is closed tight? I've had mine not quite shut and it causes the horn beep and I though it was closed but wasn't......
There is an upgraded metal hinge for the center console armrest. Mine broke a long time ago and I replaced with the upgraded metal hinge. Not to difficult, about 30 minutes.
