I got this install kit to put in a 4 channel amp and a capacitor. In order to accommodate all the power and ground cables I needed to run I had to buy a few more ring terminals. It was also a little inconvenient that the kit didn't come with any speaker wire. By far the biggest problem was the fact that the RCA's didn't work! Luckily I had another set at my house to use. I would say if you want a better kit for not very expensive, spend the extra money to get a better Absolute kit. Nothing beats good wire though, so if you have the money, go with Rockford Fosgate or Street Wires.
