[QUOTE="Justin braaapp, post: 8257415, member: 655905"] So the other day I was playing my system pretty hard when the sub cut out for the first time. it came back on almost instantly so I didnt think much of it until today when everytime I roll the volume up it cuts out and will come back on and then cut out again. I have a fi sp4 15 wired down to one ohm on a crescendo bc3500. Ive been running it on my stock alt which is a 120 amp alt with the big 3 and a xs d3400 as my second battery. I have a volt meter hopoked up and ive seen it drop to 11.8 twice in the time ive had this setup(about 5 months) but it is pretty much always in the mid 12's on heavy songs like decaf or djsnt and always at 14v on regular music like country/reggae. I havent had a chnace to check anything out due to work but I will when im off tonight. I took a quick look and saw that the heat sink on the wire coming out of fuse going from the second batt to the amp had melted into the fuse terminal. Im not sure if that would make the amp cut on and off but if anybody else has any suggestions I would really appreciate the help. Thanks ahead of time [/QUOTE]
