I have a set of the same speakers installed with the same adapters, I didn't need to reverse anything. Adapter plugged right to stock harness, then the terminals straight to speakers as is.

 

Yes the harness plugs in, but it's polarities are reversed. Why is this important? glad you asked?:smile: All 2 or 3 way speakers (speakers that have a woofer and a tweeter) have a capacitor in line with the positive lead on the speaker to filter the low frequency out of the tweeter, when the polarity is reversed, that capacitor is bypassed. The speaker will still work, but bass frequencies are going to the tweeter which diminishes the sound quality and life span the tweeter.

 

this is the pin out for the Cherokee(KL)

Left Front Door and dash
Grey + Yellow = Negative
Grey + Violet = Positive

Right Front Door and dash
Dark green + Yellow = Negative
Dark Green + Violet = Positive

Center Dash
Grey + Brown = Positive
Grey + Orange = Negative

Left Rear Speaker
Grey + Light Green = Positive
Grey + Dark Green = Negative

Right Rear Speaker
Dark Green + Light Green =Positive
Dark Green + Grey=Negative


D-Pillar (rear tweets)
Right Rear Tweet
Grey + Dark Blue = Postive
Grey + Tan = Negative

Left Rear Tweet
Dark Green + Dark Blue = Positive
Dark Green + Tan = Negative

Subwoofer (Dual Voice Coil)
Grey + Brown = Positive 1
Dark Green + Brown = Negative 1
Grey + White = Positive 2
Dark Green + White = Negative 2

The answer to you question is yes, the Metra adapter's polarity is reversed.
What I did was cut the speaker prongs off the adapter and solder the wires directly to the speaker (black to positive)

 

After reading several reviews on the necessity to reverse the polarity, I simply used a finishing nail to push back the plastic tab holding the wire in the Molex. I then simply switched the locations of the wires inside the Molex and all was good. The speakers sound much better than the stock units. Much less bass but the factory speakers had too much bass for me

 

I got the Kicker 3.5" dash speakers installed. I was able to turn the treble back up a bit. Sounds weird but the dash speakers seemed to have added some bass.

 

@stungjoe

What adapter did you order for you dash speakers?

 

Metra 72-6514

Sorry for the delay. I traded the Cherokee in for Grand Cherokee and don't come here much.

 

My Cherokee is 2016, what year was yours??
