Please, I need some help

[YokiNovvaa]

Greetings to everyone, i found some old speakers, a center sound bar and a subwoofer in my storage house. I will give you an example on pictures. Please can anyone tell why the speakers and center sound bar dont work? The subwoofer works and I can hear a little bit of sound when it plays music but the speakers and the other one just making a sound like (ssssss..)
I am really sorry for my bad English but I tried everything that I know and can't find any solution, I found this forum so I can ask for help and I really wanna use this sound system on my TV. Please.

How and to what are they connected?

So yeah, the speakers have 2 wires (black and black with a white stripe) but at the end I've converted to rca so I can connect at the back of the subwoofer.
Then for the sound test, I connect my mobile from mini jack to rca to test if its working, well it is but not the speakers.

Are you consistent in using the "FL" and "FR" inputs and outputs on the sub?

Yeah but no sound on the speakers.
Maybe I am wrong with input, I've made a mini jack to rca cable and I connect to "FL" and "FR" inputs but still the same problem

Be sure you wired the speaker RCA plugs correctly:

Can you jury rig a connection from a source directly to the speakers eliminating the sub from the picture? That way you could test if the speakers are working at all.

I'll try making the rca cables again with the post that you gave me, thank you.

Can you explain me what exactly you mean (jury rig). Thank you very much

jury rig is an English expression that means to improvise, using the available tools and materials.

The speakers are they passive ? If it’s just wires coming out of them ? The rca outs on the subs are supposed to go to active speakers with built in amps ? I assume ?
