Ok, I've had my Ampeg 8x10 for probably a little less than 2 months. I've been playing through a B2R and just got a Crown XLS 402 power amp the other day This gives me close to 750 watts. It sounded amazing and full, the exact tone that I wanted, and I never turned it up more that 3/4. Today I turn it on and I've got it about 1/2 way up and all of a sudden theres a fuzzy crackling noise. I mess around with some stuff and it continues everytime I play a note, I even checked all the chords. No matter what I do, theres still that crackling. Is this what happens when the speakers blow? What do I do now? It should be under warranty, but I don't know how I would go about getting it fixed.
