I was listening to music through my galaxy s4 plugged into an ipod dock using an auxilary cable and I thought it would be cool to try to plug in a subwoofer (I'm dumb), so i used a headphone splitter cable and plugged in another auxilary cable to the subwoofer and the original one into the ipod dock. I was listening to music fine and then my dad had another old (atleast 6 or 7 years old) subwoofer sitting around and he plugged it in instead of the other one that I was using to test to see if it still worked. It made a loud bass noise that did not match the music I was playing at all, so my dad just put it back away and decided that it doesn't work anymore.... After he left, I realized that there was a static noise coming through the ipod dock and no music anymore... I though that this was just the ipod dock that was broken, but then i tried playing the FM radio and it still worked fine.. I told my dad that I think the subwoofer broke the aux in on the ipod dock and he freaked out and said that I shouldn't have been messing around with subwoofers. Now I am trying to listen to music through my headphones on my GS4 and all I hear is static. The speakers work fine and everything else works fine on my phone still but I just cannot get anything to come out of the headphone jack other than static.. What are my options? Was it really the old subwoofer, or was it because I shouldn't have been hooking it up like this in the first place? Is there any way that I can fix my phone on my own? Thanks.
