I have the base 6 speaker system. Today I installed the Infinity Reference 3032 CFX dash speakers. I also installed the 600Hz bass blockers. I wanted to ensure that the polarity was correct and the adapter I had was also mis-wired. So I had to re-connectorize them to get it right. BTW, my factory dash speakers were wired correctly from the factory - positive wire to positive / negative wire to negative on the speaker. My truck was built in August 2020.
I actually did the driver's side only at first and used the equalizer to compare the sound left to right. There was no question about the improvement in sound quality and clarity. I also noticed that yes, the dash speaker volume is greater now (due to the ohms as discussed many times here in this thread). But it is a way better balance overall. I used the equalizer/fader/bass/treble/loudness settings to find settings that are great for me. Most of the time, I drive solo in my vehicles and I use the balance to pick up more sound from the passenger side speakers. Other than in my very small BMW Z4, I do this in all of my vehicles. If my wife joins me in the truck, I move it back to the center. After this install, I found that adjusting to the passenger side and to the rear a bit was perfect. A huge improvement in overall system sound quality. Still decent mid and bass punch from the door speakers front and rear. Highly recommended upgrade.
Thanks for all contributors to these threads for helping me narrow down my options before proceeding.
