There is only nokia sub behind the seat backrest. But where is the amp?

There's no separate amp. Active rear speakers has amp built in them. That's why there's 5 wires for each speaker.

Aaa, god damn it. I disassembled half of the car looking for this bloody amp... Thanks for info. Are all these wires going directly to the socket that plugs into cdplayer? Its a lot of wires. The thing is that the rear speakers and sub are not working. Cd player is an aftermarket. Also found some cut wires under the dash. Could that be the reason the rear end is not playing? If so i am not sure where to connect them because the socket seems full. Also there is one wire (broun) with an OE connector. Dont know whats that for. Probably was lugged into OE player. Any input wiuld be very much appreciated

Forgot to mention, there is also a cd box in the trunk. Can i make it work from aftermarket cd player?

I'd say rear speakers doesn't work because active rear speakers are using OEM headunits line-out outputs (large green/yellow/blue connector) and none of aftermarket headunits has plug&play socket for that. Adapter is necessary to make them work. Post a picture of those cut wires if possible.
Brown/? wire with single connector is for antitheft alarm. It connects at the back of OEM headunit and if someone steals headunit disconnecting that wire, alarm will be activated.

Thnks again. I will try to find some time during the week to take a pic of the cut wires. I gues with pictures will be easier to talk😊 Thanks for info.
