Irecently bought an amplifi line 6 75 but it looks like the cabin was opened and it didn't turn on. I open it and the inner power cord was conected the wrong way, I fixed it and now it works, but I don't know if the speakers are complete or there are some missing or switched, I can see the main speaker it is a 15 wats 4 ohm, and a pair of plastic cover speakers in the upper of the cabin, and in the botom I can see a pair of kind of 3 inches empty cilinders I apreciate any información just to make sure if that it's the proper way or it is something wrong thanks
