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.
You are so right. I replaced the front door speakers in my 2013 base V6 today using a pair of Pioneer 3 way speakers and the Meta wire harness. When I first hooked up the new speakers they sounded OK but not as good as I was expecting. Then I remembered reading about the Meta's possible polarity reversal. I took the harnesses off and cut the wires and spliced them in reverse, hooked the speakers back up.... What a diff, like night and day. CDs sound really good now.
