Connecting two hi-fi systems via RCA

Solved

Good evening everyone,

I was wondering if there is a way to connect two hi-fi systems from one audio source.

The first system is a Samsung MX-J630, and the second is an LG CJ45. Both have RCA IN input as well as a Bluetooth receiver. Unfortunately, there is no line out.

The manipulation to connect the two speakers of the first system to the second seems complicated given the proprietary connectors of Samsung.

I thought of something, I have this type of cable:

Assuming the source is a smartphone, a first male 3.5mm jack cable is connected to the above cable (female jack to male RCA) which is itself plugged into the first system.

Then, I connect a male-to-male RCA cable from this part:

to the other hi-fi system. Can this type of installation work? If not, how can I do it?

Thank you in advance, Simon.

    With your LG, you don't have enough sound?

    The problem, if you want to connect the speakers, is the impedance...

    If you connect the speakers in parallel, you risk frying the amplifier!

    You can connect them in series, but it will consume quite a bit of power

    So we have the basic setup



    Then we have the parallel cable = Dangerous for the amplifier


    And the series wiring that will work but will deliver less power


    As for the Samsung connectors, cut the wires about 10-15 centimeters from the cable and put on terminals, like the ones used for car stereos.

    Good evening,

    a lot of things are possible with sound, but first I'd like to understand your goal?

    Would you like to have sound in 2 different rooms or have 4 speakers providing sound instead of 2?

      I would like to have "more sound," to have the 4 speakers producing sound by connecting the same audio output to the RCA inputs of both amplifiers. Thank you for your response :)

    By doing this, the first thing that is likely to happen is to have a sound delay between the two HiFi systems.

    Can you show me these proprietary connectors as you mentioned?

    Do you have a separate BT receiver or is it in one of the two systems?
