Subwoofer install to intellilink R4.0

See All Pictures

I've been researching and doubting a few months before firing the shot to install the sub in my new Corsa E 5d (Leased car - so no permanent modifications!).
I had some bumps to take (maybe mental to even start doing this to a new car): No converter wiring can be found for the Corsa's intellink R4 system to DIN or something. Where to take power? How do I even get behind the headunit to reach the Audio signals? How do I hide all the wiring? Gound connection?

So, may this post help others.
It took me about 4 hours to completely install the sub.


Final result: Pioneer TS-WS710A under double bottoms in the trunk

Connections to Head Unit (Intellilink R4.0) with custom made splitter, this is a leased car: so no permanent modifications

Power for the Amp is taking from the fusebox. One of few options I don't have is a sunroof (25A), so I used the fuse connection for my Amp (15). The remote signal is taken from the 12V Cigarette plug.

All wiring runs at the drivers side hidden behind trims and under the rear seat (real tight fit to get something under the rear seat)

Great pictures!

Many people have asked so...
How in full detail did you take out the intellilink unit? In particular how did you take off the dash and intelly surround without damage?

** Disclaimer: When I say though clips: that's from an amateur point of view. One who doesn't have special affection with cars or knows anything about cars or works mechanically on cars. Maybe this standard in car industry, I don't know, It's just my outsiders view.


(The flowing pictures are actually taking during the re-assembly process afterwards.)

Image

You have to use real force to get the first clip undone, from the moment you can use your fingers: do so. But be wary to not overshoot and really break in pieces.
Image

ONLY use your fingers from the top right side (respectively top left side on the left hand side of the display) to loosened up those clips. Those are really though, like really tough, like you will get sweaty while getting those 2 clips undone.
Image

As I did not know where the clips were, I've tried a lot. The biggest trouble spot seemed to be in the corner so I used multiple plastic prying tools to gain more leverage there because I couldn't get my fingers under. Which have left some marks there, unfortunately.
Image

5 More screws, and the head unit/silver box assembly comes out easily.
The dual vent (above the display) just pulls out without any problems.
Image
As you might have noticed, I disconnected the 2 connectors to the fascia to work more easily.

New pictures also added to Imgur album.

Standard electronic single-row connectors with 2.54mm pitch glued together to make to required number of pins of 2 rows. Wired with 24AWG silicone wire to split the required signals.

Something like this (but with more pins, 2 of these glued back-to-back):

1 Side is female (as in this picture) other is male. The splitted signal goes to the XLR connector.

Hey, I'm referring to the brown connector you have in the back of the Intellilink unit (the physical 20 pin multiconnector) you tap off the original then have a second. I've looked everywhere to try get one and can't find them anywhere!

The brown connector? I don't know, it is the stock connector on the wiring harness connecting to the head unit. I wasn't been able to find a fitting Y-spitter for the connector.

Dear DX2Z or anyone else with experience in this topic

I have the same R4.0 in my Astra K with the same old brown (and white/grey) connector(s).
I'm about to replace all my speakers and add a subwoofer to the trunk, all driven by a 5ch amplifier. I'll need a good quality LOC for this, but I am not sure yet which one I should choose. Meaning only the LOC will be directly connected to the brown connector, nothing else.

Do you use the factory speakers of the car? (I mean the door speakers, not the sub of course)
Is the R4.0 testing the speakers or is it only Navi900 that is doing it?
Did you have error codes or anything else ?

I am looking forward to your reply and thanks!
