Had a quick question about fuses and stuff. I have a Sax 1200D, MS-8, and a PPI P900.4 (probably going to add a small 2 channel for rear fill). I was going to run 0 gauge wire to a distribution block with an inline fuse before the block what size fuse should I get? Also do I need fuses after the block? I know I'm going to need one for the MS-8 but what about for the other amps?
