Hi. Sorry, we are not able to answer in Finnish at the moment, so I hope English is okay.
I understand the question to be: "Can party boxes connect more than two to one using RCA cables?"
As the Partybox speakers are designed at the moment, you will have a delay between each Partybox when you daisy-chain them, and the delay will accumulate. It is not long, around 50 ms, but that is enough to present problems in certain setups.
So, either you must go with the wireless connection, which limits your use to two Partyboxes, or you must use an audio distributor box to feed all Partyboxes with identical signals from the source through the distributor box.
I hope this helps.
