I bought this pair of speakers to use for the RCA output from a Roland DJ-202 USB DJ controller. The speaker connection seems simple.. RCA out from controller to RCA in on the right speaker. Then use the regular speaker wire to connect the right speaker to the left, passive speaker. I have them hooked up like that, set the switch on the right speaker to"line" (tried as phone but was very distorted and still no sound from the left speaker. Is there something simple I may be overlooking? To troubleshoot I changed the source to use the AUX input from my phone. The right speaker sounds great, but still nothing from the left side. I re-seated the speaker wire a few times in troubleshooting.\
Any advice anyone?
