How I Corrected My Impedance Mismatch

Last year at this time I installed new speakers in my mustang, detailed here:

https://www.allfordmustangs.com/forum...y-mustang.html

Unfortunately I experienced moderate to severe distortion starting at 50% volume due to an impedance mismatch. I had some time off again this year, and fabricated a custom wiring harness adapter to correct the impedance mismatch.

How I did it is detailed in attached.

I am looking to replace my factory speakers and read your install guide, and now I just read this report you did on correcting impedance. I am not as technically inclined as you are at this type of thing, would it just be easier for me to just install 6 ohm speakers and not have to correct for impedence or are 6 ohm speakers generally of lesser quality?

If you just buy a 4 Channel Amp that is 2Ohm Stable then you can run the fronts on one channel at 2 ohms & the rear on the other at 4 ohms....
