Well I guess yours is LHD?
Mine is RHD and the Radio/Amp box is where the white box is on this photo.
Right up against the side with connectors going in the bottom

Not my car in the pic but just to demo where it is situated.
Mine is NON Nav so maybe that make a difference too...

Hi Airblade750,
thanks for your reply.

Yes, my AstraK has the guide on the left side.

if you refer to this:

the plug cables i see:
Image

they are not the same size you find in the door for speakers:
Image

so if that is the amplifier, I guess it is the input cables into the amplifier, but not the cables that go from the amplifier to the speakers. Is this so?

My goal is to try to intercept the amplified cables (between amps and speakers) because having to extend them until the trunk would lose less audio details than the "weak" cables that go from the car radio to the amplifier.

my doubt is: if they are in the central console?

Hi there :) simo_zio

If you remove the plugs from the radio/amp unit under the dash, you will see that the cable colours match the ones that go to the speakers. The yellow/black ones in your pic are in the plug but you will not see them until you remove the plug from the radio/amp unit.

Also, you mention, "I guess it is the input cables into the amplifier" and, "lose less audio details than the "weak" cables that go from the car radio to the amplifier".

There are NO audio signals generated by the, "head unit/display". It is simply a display/control interface. The only analog audio signals are those high level/speaker outputs coming out of the amp/radio unit.

Colours should be something like this...

Green Left Rear Speaker [+]
Blue Left Front Speaker [+]
Yellow Right Front Speaker [+]
Blue/Black Right Rear Speaker [-]
Brown/Blue Left Front Speaker [-]
Yellow/Black Right Front Speaker [-]
White Right Rear Speaker [+]
Green/Black Left Rear Speaker [-]

Hi Airblade750
thanks for the explanations! :D

Therefore, for these connectors:
ImageImage
I mapped the colors, although some are not clear :? .

ImageImage
(however either the cables get bigger afterwards, or they don't go directly to the speakers, they are half the thickness. :? )

Anyone know where to buy adapter cables / connectors to not have to cut them? :?:

Thank you all for your patience, I am trying to post as much material as possible for future benefit.

Any suggestions on how to get ignition live from the boot? I have the Sports Tourer with fuse box in the boot. Maybe tapping some of the fuses back there?

A big thanks to christ_106 for the location and colour coding for the speakers on my Astra k 1.6 cdti 2019.
Made my job a lot easier for me to install an Audio Control LC2i line out converter. So I've left the original head unit in with the following upgrade. All doors have been fitted with dynamat.

Front doors : JL Audio ZR650-CSI components
Rear doors : JL Audio C5-650X Coaxial
Subwoofer : JL Audio HO10W6v3-D4

4 doors are running off JL Audio HD600/4
Subwoofer is running off JL Audio HD750/1

I cut out the stock tweeters and sat new ones in the original brackets with mastic. I fitted the bass control knob in the compartment below the main lights switch.

Took quite alot of time and labour but it does pay off. Sounds amazing!
