Ive tryed swapping the leads earlier and I am using the bose controller. I am using an old peavy amp deca 1200 i believe its output is 4 ohms. Only one channel works on the amp so im using both the out puts on that one channel for both speakers. However i had the speakers working perfectly earlier but then when i turned them back on the amp started cutting out and i had the same problems as before, I couldnt play the music loud enough without the amp cutting out. I dont understand how they can be working perfectly one moment not working at all?
