The red power wire from your amp wiring kit may have a fuse holder installed. If so, go to step. If not, find a good spot close to your battery to place your fuse-holder (included in the kit) — less than 6" from the battery is best. Cut a short piece off the end of the power wire (to cover the distance from the battery to the fuse holder location), and strip the insulation off both ends with a wire stripper.
Crimp the terminal ring (included in the kit) onto one end of the short piece of wire, and crimp the fuse holder onto the other end. Strip the insulation off the end of the red power wire that leads into the passenger compartment, and connect it to the other end of the fuse holder.
Fuse installed on power wire, and secured in engine compartment.
