So I just got the Eris E3.5 today and it's used (from Amazon) and they said it was in "great" condition, but turns out, it isn't. Whenever I plug the red and white wires to the input in the back of the main speaker, the aux at the end of the wire doesn't work. But, if I insert an aux to aux line in the front saying "aux in", it only produces sound on the right speaker but only static on the left speaker, like, really quiet static; you have to put your ear against it.
I've tried everything from plugging it in correctly, putting the white wire on the red and vice versa, etc., and still the same old problem. Can anyone please help? Thanks.
