Well of course I cannot tell you why seller says it is wrong.

You might consider not to do business with seller if he consists in not being helpfull. :think:

As I stated before, I don't think you want both subs not playing together so I don't think you should connect one sub to the left channel and the other to the right. I would connect both subs with each an own speakon cable. I would connect both yellow cables together to left +, both red cables to right + and both black cables to left -.

Next problem:
https://rel.net/blog/2015-07-23/how-to/ ... ingle-amp/

They wrote:
If connecting 2 RELs, connect the black wire of each REL to a negative speaker terminal of the corresponding channel; twist together the red and yellow wires of each REL separately and connect each pair to the positive speaker terminal of the corresponding amplifier channel. In some instances, this will result in exceptionally high gain (output) from the RELs. If it seems simply too high in gain, please remove either the red or yellow wire from the twisted pair. This will reduce output by half and restore a natural dynamic.

If you are connecting to a Class D amplifier please consult the How to Connect to a Class D amp guide regarding the Black Wire grounding technique.
If you are connecting to a Class D amplifier please consult the How to Connect to a Balanced or Differential amp guide regarding the Black Wire grounding technique.
And I have got balanced and unbalanced connections in my amp.So is it problem? but I ve got A/B amp...

Hi Hoewie,

I will get subs on Tue/Wed.
I will try them on a different amp, just in case .
If I connected them at B speakers terminals, I have to turn the switch to A+B speakers .
It should be ok.

So Hoewie, I tried it on my old amp Pioneer SX 450.
It´s got the switch for speakers+ turn it off together.

power OFF
Speakers A
OFF
Speakers B
Speakers A+B


So I had 3 wires going from speakon(connector for high level on the sub).
I soldered red + yellow wire together and connected it to R+ on the terminal for B speakers.
Black wire I connected to R- on the terminal for B speakers.
+exactly the same I did for the left channel.
OK.It started to play, but when I turned the switch to power OFF or OFF position, it started to hum.

OK I tried to remove yellow wire and connect only red and black.The signal was weaker , but hum was still there (on those two OFF positions).
OK, I said to myself when I was connecting my better amp.If it was connected with satellites to the same terminal A for speakers, hum problem will disappear.But I was thinking more...It wasn´t enough space to put tiny wires to the terminal with wires for satellites.
What´s the difference to put it straight to terminals on my satellite speakers?
So again:
I soldered red + yellow wire together and connected it to R+ on the terminal on the right speaker.
Black wire I connected to R-.
+exactly the same I did for the left channel.

OK I did it.The sound is very nice, without hum.I turned AUTO ON on the sub, so without signal It is going off automatically.

So I have two subs for stereo listening and I´m happy. :whistle:

Hello Jan. Great to read that everything worked out fine. Are you going to investigate why the Pioneer SX450 is humming with the setup you made, because of course something can be wrong with the SX and the humming is not due to the connection of the subs.

No, many people wrote about this problem.
I think if I connected it to another amp with OFF positions it would be the same.

SX 450 is 100% OK.

Active sub doesn´t like when nothing is comming from the amp.
If I connected these subs the same way as I did with another amp, it would be playing without problems .

So if you would connect the subs and satellites on speakers A of the SX in the way you connected it to your better Amp, in would not hum?

Hi Hoewie,

not at all. Be careful about the polarity.

Of course :)

So connecting the subs to Speakers B and the satelites to Speakers A is not recommended. Just connect it all to Speakers A and everything is fine. :D
