Crutchfield Customer Review (What's this?)
The included blue/white wire was needed in order to get sound in my car. This is apparently because mine has a factory amp. It came with very little instructions, so when I hit this complication I had to go to forums to find an answer. It worried me that because I'd used the blue/white wire when connecting the harness that I wouldn't be able to connect my stereo to an aftermarket amp, but Crutchfield support came through and confirmed it was okay to connect multiple remotes... Everything works.
Pros: Crutchfield was helpful and even got back to me over a holiday when I ran into a complication.
Cons: None. It all worked after I sorted out my minor complication.
