Passenger second row and hatch speakers not working

I installed the Kicker speaker set from Trail Grid Pro a few weeks back. (Sadly I don’t remember testing each door as I installed. Hello Captain obvious?)

My second row passenger door speaker and the subsequent hatch speaker on the passenger side are not playing. I know they run in series. I removed the door on the second row and hooked up the original speaker. Still no sound.

What should be my next test? The front passenger door plays. I’m not very techy when it comes to things like this.

 

Next step would be verify the hatch speaker is connected.

 

Would that have any bearing on the second row speaker?

 

Like you said yourself, they are wired in series so they both have to be connected and working to make sound.
