Need help connecting 2 different sets of powered speakers.

I am trying to connect 2 different sets of powered speakers altogether. 1 set is Pyle and the other set is Rockville. All speakers have a inline and outline port for the speaker line. I want to connect all 4 together to get as much sound as possible using a aux cord since my bluetooth on my laptop is losing connection from time to time. I wish I was able to post a image but I cannot. Someone, anyone please help. Thanks very much in advance.

you really should use a mixer or some sort of audio interface. rca input (unbalanced) will very frequently create loud buzzing and humming. it sounds like you should just be able to jump all the speakers in 1 line if they all out xlr or 1/4" outs
