I got this wiring kit for a full system upgrade to my 2016 Subaru Crosstrek. Because I was adding an Amp, Sub and replacing all 4 main speakers, I wanted a kit that had Power, Ground, speaker wire, and a full set of RCAs. This was the only kit I could find that came with a 6 channel RCA for a reasonable price. The great thing about this kit is that it comes with everything you need if you’re installing a 5 channel amp. The wire is all true gauge spec and I didn’t have to purchase any additional wiring or accessories to install. This kit made a HUGE difference because there was enough wiring for all the parts of the system and the quality of the wires is very good, so for the price, it added tremendous value to the system. I easily could’ve spent three times as much for the same wires if I had bought them all individually.
