Wiring kits are universal. Usually they come with a 2-channel RCA, so you have to buy another RCA cable. There are many people who are comfortable paying no more than $25-30 for a 4 ga amp kit, but I prefer the quality you get from a kit that's around $50-60. The power and ground wire is generally a higher strand count, the jacket is more flexible and easier to work with, the terminals are better quality, the fuse holders are better quality, and so on. It's small differences that become apparent when you've seen a bunch of different amp kits.
