Not only was the online ordering reliably accurate for make and model selections for my stereo receiver but the installation information provided was easy to follow and uncomplicated. This was my first time to install a stereo and it was simple thanks to the great information Crutchfield provided.
Tip for consumers: I went with the pre-fab'd connection harness, I highly recommend this for first timers. Connecting all the wires yourself was the thing that most concerned me with my maiden install attempt. Crutchfield eliminated that concern for me.
