Could faulty fuses cause two tweeters to blow? I had no sound coming out of the original P-Audio in my GK Neo 410 8 OHM after talking with their service dept. yesterday they told me to do a 9 volt battery test on the wires connected to the tweeter if the fuses looked alright to me because this crossover do have two separate fuses in it. The p-audio was blown so I put in an foster tweeter that I had and I heard it pop right after I turned the amp on. I use the correct speakon cable from GK and my cab is used with a 700rbII head, any help would be appreciated. I am going to take advantage of the protection plan from GC but this doesn't help me for my gig tomorrow.
