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.
