How to connect this multitude of wires

Hello,
Without knowing the references (Brand and model) of this car radio, it's impossible to tell you more..
Because if the wires are "multiple", the number of car radios on the market is a thousand times greater.

Hello baladur13, thank you for your response, I will indicate everything that is written:
on the front of the car radio CD player I have: TUNER LIST that's all
on the side:
Model: RENRDW100-10 RENAULT
UNDER THE BARCODE: 8200247962TQ157
PROD: FD0404380220301
On another label there is:
604 B74 3930585 2
Radio 7962
CD change front:
BGRR0632591982
There are 19 wires in total on the two connectors.

On what model and year of car is this part mounted?

Good evening baladur13
not having received a response, I looked at your first address:
the socket with 4 brown wires and 4 orange wires is for the speakers:
I connected 4 speakers of 5 ohms.
the other socket next to it, the thick black wire is the ground (negative) of the unit, No. 8
No. 7, sand color, is the + after contact.
No. 4, thin red wire, is the + permanent (to keep the memory),
I haven't connected the other wires!
when I connect the 12 volts, nothing happens,
if the unit is off, there is no beep when pressing the buttons,
if I turn it on, as soon as I press a button there is a beep.
the CD player works electrically (the CD goes in and out)
therefore, I disconnected the battery for a few minutes and reconnected, to enter the radio code, and I validated (several attempts with button 5 and also button 6) after a few seconds I got the validation beep
but no sound... (and still the beeps when pressing the buttons)
No. 2 worries me because it is not connected so silence could be the cause?
can you help me please THANK YOU

note: for your information
1 = automatic volume control
2 = mute
3 = not used
4 = + 12 volts permanent
5 = switched 12 volts output (electric antenna)
6 = car radio lighting (controlled by the vehicle lighting)
7 = + 12 volts after contact.
8 = - 12 volts
