Chevy Tahoe electrical problem prevention questions

[SpdDmn713]

I am trying to get everything lined up for my install into my Tahoe. Everything is stock in the truck right now. I will be installing a 1400w system with 1000w sub and 400w on front comps and rear fill. My question is what do I need to do to prevent electrical problems, or what should I do to satisfy that 'an ounce of prevention' thing. I am planning on doing the big 3, and I have a 600cca battery and a 105amp alternator. Do i need to upgrade the battery or alternator? Should the big 3 be enough to increase the operating efficiency of the electrical system? Do I need to put in a Cap? if so how much of one? Thanks for the input! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
