Ok guys and gals, here goes, I have searched and read through pages of material and I still have some questions about wiring an amplifier. I have a 2013 2275 RCW with the dual battery set-up and the BlueSea 150 distribution block. I am mounting a Sub and amplifier in the console and the amplifier is a 200Watt MB Quart. Some of my questions are as follows: 1. I want to run the positive and negative wires back to the BlueSea distribution block, is this possible and if so what size/type of fuse recommendation? 2. What gauge wire would be recommended, is 4 good? 3. With the under deck wave shield, what route did some of you take with the wiring?
