Noise when Bluesound Pulse on and ampli out

Hello everyone and thank you in advance to those who take the time to read this post.

Here is my configuration: an analog ampli with 2 wired speakers, a Google cast box to listen to Spotify or Daphile. Everything is OK. 

Furthermore, 2 pulse bluesound speakers that I rarely use because I have to go through the proprietary bluOs app which is not very sexy.

But my old wired speakers take up space and my wife would like to keep the 2 light and discreet bluesound speakers. Hence the idea of ​​replacing the 2 old HPs with the pulse via their analog/optic in port and a 3.5 jack socket.

I bought soldering jack sockets. At each jack socket I soldered the "red" + wire from the old speaker to the so-called hot tip of the jack and the black wire - to the ground of the jack. I activated analog mode on the blueOs app. It works perfectly except that when I turn off the ampli I have a whirring sound in the pulse. I have to pause the pulse via the blueOs app so that the noise stops. Could I have soldered the cables incorrectly, reversed? THANKS

  oups, thanks for your answer about the risk of connecting directly from the ampli speaker outputs. I didn't know.

  So ok but i do not understand what you mean writing "a tape out or pre amp out from the amplifier". What tape means ? With a preamp whihch kind of connection with the pulse ? Wired ? wifi ?

  Hi, great it works. Don't realy understand why but it works !!!

  If i connect a RCA on tape output and set source on "aux" for example (when my google cast is connected) i listen spotify. If i select tuner source i ear my radio etc...

  The only "pb" is i cannot set the nivel of the sound on the ampli (or on tape) but on the phone. I set nivel max on blueos app then i set the nivel in spotify or on the smartphone.

  Hi again,

  I listen my CD or vinyle music with RCA on tape output to one of the pulse. But i would test your solution with a pre amp.

  2 questions :

  Do i connect the pre amp between the tape out put and the pusle ? ,

  Do you have any examples of not too much expansive pre amp models ?

  Regards.
