I have two amps and the power wire from the batt. is an 8 gauge wire but it goes into a fuse box to hook up more than one amp and from the fuse box i have 4 gauge wire going to two amps is that bad also i had to cut off some of the gold wires that carry the power off the 4 gauge because it wouldn't fit in my amps and i dont know if this matters but one amp is 220 watts and another is 1200 watts oh yeah and i do also have a capacitor connected with the 8 gauge wire
