Hello all
Was wondering if anyone has a solution to the following or can point me in the direction I might get an answer. Basically my KRK rokit speakers work fine when I play music from my laptop, using an aux from the laptop to a rca converter with two male extensions that plug directly into the speakers. However when I use two rca male-male cables to connect my decks directly to the speakers, only one speaker works (the same one every time, no matter what wire configuration I use). This makes me think that one speaker is broken, however how can it work when connected to a laptop and not with my decks?

Any help is appreciated!
