Connection 4 x S1

I am trying to link 4 x S1 speakers and having problems. I am able to link speaker 1 and speaker 2 using the party mode on my iPhone with no problem. I want to use 4 speakers, so I then attached a lead from speaker 1 output to the input of speaker 3 and the same with speaker 2 to speaker 4.  When I turn on speaker 3, all speakers work for about 3 seconds and then  everything cuts out. Any suggestions?

That sounds like it should work. Please see this article for notes about how you should connect S1 Pro #1 to S1 Pro #3 and S1 Pro #2 to S1 Pro #4.

S1 Pro Daisy Chain Settings

Is that how you have things connected?
