2021 JBL subwoofer output wire color question

Hello, it’s me again. I’m sure I missed a thread that discussed this but I wanted to ask about the color of the wires if the JBL sub on the 2021 tundra. I noticed they are black/green. Is it fair to assume the green is positive and the black is negative?

 

I would think the black is negative. You can use the below link for reference that may help.

Get yourself a multimeter and you’ll know for sure.

Thank you for this. I can grab a cheap DMM from harbor freight or Home Depot to be sure.

The diagram doesn't show them to be black and green.



Off the amp pin 5 green is + and pin 12 violet is -



At the speaker/sub pin 1 white is + and pin 2 lilac is -

 

That’s interesting! But yeah the wires and plug going to the sub are green/black, at least in my case. I do appreciate the help though!

 

Did you ever confirm these colors?

 

I just assumed the green was positive and black was negative. It’s been fine although I probably should’ve busted the multimeter on it for good measure but never did.

I installed mine based on the info below, which is based on JRT info.
Refer to post 341. This is in alignment with a what came from JMT as well.

"As you can see, white now goes to green and blue goes to black. With that being said now the green goes to the black connector on the sub and the black wire goes to the red connector."
