THE pico fuse in my F900BT blew and I completed the circuit using a 1A Glass fuse. That fuse then blew, so I just completed the circuit unfused. Shortly thereafter, the sound started fading in and out (for my fronts and rears). Then eventually, the sound just cut out all together from my 4-Channel amp. The Subs still hit normally. Is this an issue with my 4-ch amp, or the headunit? I'm beginning to suspect my 4-Ch amp dying was the cause of the pico fuse and glass fuses blowing. I'd like to get this fixed before my road trip in two weeks. Any suggestions?
