What guage power cable do you have running from the Battery to the Distrobution Block. And from that, what guage power cable do you have going to each amp? From what i gather you have a distrobution block with 2 fuses in it yeah? but what fuse do you have between the distro block and the battery? And also as Mark said, use RMS, not Peak Power, because peak doesnt mean much these days, as alot of brands use it as a marketing tool.
