    Hey everyone am new, and plan on doing an alternator upgrade to my tacoma 2.7l. I am going to do a 250 amp alt with 2 xs power batteries d 3100 which is going to be supplying power to my two audio q 2200 amps. Am getting real confused since this is my first time. How big does the wire have to be from alt to fuse box? is 1/0 gauge safe? how big should my fuse be from alt to fuse box? What will happen if i have too small of a wire or to big of a wire?

    I am new to this so any of your help i highly appreciate.

    THANKS :)[​IMG]

    go to http://www.bcae1.com/

    on the right side there are a bunch of topics, scroll down to #16, Wire. Read that.

    Main fuses are sized to prevent wires from chaffing through the insulation and starting a fire. I actually haven't looked yet on my Tacoma, but OEMs typically put in a fusible link for the battery to fuse box "fuse". If you upgrade wiring (like what is known as the "Big 3") then you should upgrade the fusible link. For the wire from battery to fuse for amplifiers, it should again be fused to protect the wire. At the amp there is typically a fuse to protect the amp - very few amplifier OEMs did not install one (Xtant comes to mind as a company that didn't). All the above I wrote is probably only approximately correct due to how much I was willing to type - read #16 above until you understand what it is saying. Reading just about that whole site wouldn't hurt none - you'll know more about car audio than probably all of your friends.
