They're basically the same price, but the difference is that your speakers will be in phase and you'll have more mids/lows (within limits of what the stock amp can support). For reference, this is the difference between the Metra adapters and the Crutchfield adapters. Please excuse the typo within the picture

I originally bought the Metra adapters (72-5600), but when I changed them out for Crutchfield's, the sound difference was huge.
I know this is old but it sounds like the Metra connectors are still wrong based on recent Amazon reviews. I did not read this until after I placed my order earlier today. I looked at Crutchfield for the correct option but they show two Metra connectors for late model Ford, none of their own brand? Anyone have a link?
