Rockford Fosgate's RFK4D 2-amp wiring kit is a great all-in-one kit for the masses, featuring quality materials and construction. It includes numerous copper strands, speaker wires, patch cables, and a fuse holder. The power and ground cables feature twisted pair, which is common in mid- to high-end cabling, and the speaker wire features two-color jackets that make identification of + and - easy. The kit also includes a maxi fuse holder, which is a quality piece. Overall, it is a good foundation for an amp kit.
