    put in a fuse that is rated at an amperage right under the amplifiers needed amperage, thus protecting your wire from overdraw.

    You should be fine running the 100amp fuse for now. If it blows later on upgrade it, but I doubt you'll need to.



    Fuc, how come when I copy and paste **** it never gives me the cool blue thing in my sig. Sonofa*****withhotredtabascosauceonmynutz!!!!!

    Jsut look at the fuse on the amp. How much is it?? That is how much amperage the amp is going to want to pull at peak power. This isn't rocket science. Now get a fuse that is either right underneith that number or one that matches it. Now your set.

    Okay, the amp's fuses are there to prtect the amp.
    The fuse that you're going to install in the power line is to protect the power wire.
    Fuse for the limits of the power wire (guage voltage/thermal limit).
    With 1 ott wire you can fuse up to: ~300 amps.

    IMO, get a 200amp ANL and be quite safe (happy).



    What the f00k happened to this place?
