CDT NF-6902 package install help

Hello,
I am new to audio and electrical tech.

I recently purchased the CDT https://cdtaudio.com/carspecific/nf6902.php package for my Nissan Frontier.

It lists a 4 ohm impedance for everything, but multimeter testing showed 2.1 ohms for the 6.5 rear fill, 2.2 ohms for the 6x9 components, and 4 ohms for the 2 inch tweeters.

Am I not understanding the specs or did they send me the wrong mids?

I would call them, but they are closed on weekends, and I would like to install them asap.

Thanks for any help.

Will the 6.5 rear fill be too loud though?~thx

I connected a tweeter and 6x9 to the crossover, then a wire to the amp input- which in turn connected to multimeter: 2.7 ohms.
~Thanks for anymore thoughts
