Well yesterday i took a long drive and my stereo was cutting in and out, like the amp and the subwoofer would turn off and then turn back on, My setup is as follows, i have a 4 gauge that is fused, running to a distribution block that is also fused, which then has 2 8 gauges one going to a 600W amp powering my speakers and one going to an amplifier powering my sub 300W and now today i get nothing, what should i do, i know its not the head unit, and the amps are not turning on, should i take out the fuse in the 4 gauge because the distribution block is fused, or what should i look at
