I have a few questions. First, I was wondering if I could use a metal connector to combine peices of wire for my power wire. I dont have a single wire to reach from my battery to my amp, but i have enough if i connect 2 peices. Second, if my amp has an external fuse rating of 200, should i get a 200a, 240a, or 250a fuse. Knukonceptz has a fuse holder that takes 3 mini anl fuses so 80x3 is 240a. Lastly, which grade wire should i use to go to my subs? I will be putting 700-800 rms to them. Thanks for any help.
