Crackling sound at quater volume, cuts out when turned up more
Sounds like a blown speaker on low notes but speaker isnt blown. cuts out completely but comes on when u smack the top. removed board, can reproduce problem by wiggleing the main harness to what im guessing is a transistor? ( the black box with all the wires going to it) checked all connections and they seem ok. could it be the black box itself?
