    Which is hooked up to two of these...
    The strips are about six inches in length, I believe.

    I am not sure if i need anything else, like perhaps a fuse. I tested this whole thing out and it does work but the test was only for a short period of time and I am not sure if for long-term usage, if I should have a fuse or resistor of some sort on here. (I am a novice with wiring)

    Thanks for any and all help.

    i dont think batterys are going to last very long in this set up
    i would rather get a 12volt adapter charger 1amp or so

    6 inch of leds is 100mA
    so 12 inches is 200mA

    the sound box doesnt say what current it draws

    in my opinion if you use a suitable wire size and you wire it correctly you dont need a fuse

    ok thank you, yeah I tried the adapter but the fuse kept blowing on it for some reason and now i the radioshacks i go to dont have the specific fuses in stock, so I am just going to stick with batteries for now, even if they dont last too long.

    Wouldn’t hurt to fit a fuse, especially if the high consumption of power eventually requires the use of rechargeables. These can in case of a short produce very high currents and catch fire.

    On the wire between the two cellpacks would be one suitable place for a fuse.

    A fuse can never hurt, but this uses AA batteries. I don't think I would bother myself.

    If you have a wall wart maybe, but most cases a non replaceable fuse is included inside the wall wart itself.
