I got my 2018 JLR in November of 2018 with the 8.4 Nav and Alpine® Premium Audio System for $1,595. It is a weekend drive and only have 1,200 miles. The speakers sounded so good much better than my 2001 TJ that had the worst sound and just did not turn radio on as had the top off.
So had some dash speaker act up and replaced them with https://www.crutchfield.com/p_108R3032CM/Infinity-Reference-REF-3032cfx.html Great sound… Do not install the capacitors, I had a long conversation with mfg. as I was getting a popping sound at shutdown and startup.
So had some PM conversations with others and did some YouTube checks on Polarity… To my surprise I have 6 speakers had a negative polarity miss wiring. So I put the Ref-3032cfx in the dash and fixed the polarity as well as used the same speaker in the sound bar.
I had to fix the 4” polarity by pulling out wires connectors from the quick connect and retest. I did not take photo, sorry but just use a good flashlight and will see a white tab that needs to be lifted up. O and lift up the back stop so the pins come out the rear like butter.
I used a FwaeH FH-168 polarity tester and downloaded the cd to a USB flash drive to play the test sound. NOTE: I could not get the polarity app for iPhone to work so got credit and purchase https://www.amazon.com/gp/product/B07MQ55QHL/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 for $14.00
Since I have a USB of the test sound, PM me and will send to you if you do not have computer with a cd drive to make a mp3 for USB flash drive.
So now I have the knee speakers upfront and need to change the polarity. I have read that you have to take the dash out to get to them… Well, on the first sunny day will see if I can get to the wires without taking the dash apart. ANYONE DONE THIS???
I hope this will help you brothers and sister Jeepers. Let me know if you need more detail….
