if by chance you have an older amp with the screw connections you should also be able to find connectros for that at the local parts store too. you don't want to piece power wire, if you don't have the full uncut length you need it'd be in your best interest to just buy a kit. Also make sure you do get a fuse holder, they're cheap and if you don't get one you could burn up a lot of things, including your car.
