Really professionally explained, thank you

I would just disconnect those speakers. The speaker location is poor for a good listening experience. Better sound is to replace the 3inch drivers with better 3inch full range, such as some of the Dayton Audio. Replace the woofers with something better. Power thenm with a 4 channel amp that has crossover for high pass and low pass, such that you can run the full range down to maybe as low as 200hz, and run the woofers below 200hz. The center channel can be run off mixed/mono with the full range, but use an 8 ohm driver. This turned out very well in mine. I'll be adding a sub in a fiberglass enclosure in the trunk soon.

I know this is an old one but maybe some can answer this….if Mazda Has those speakers crossed over how do they accomplish this in the non-Bose system? Is it via a capacitor? Can that be removed? (Cut it out and splice new wire in) If not… heck you’ve already got the car basically taken apart so why not run new speaker wire from the head unit or amp? (assuming you went aftermarket on one or both)

Yes, there's a crossover cap on those rear speakers. And while they could produce lower frequencies below the crossover point (probably good to around 600Hz), there is no baffling for these speakers to separate the L&R drivers, so you'll start getting weird cross channel cancellation and nodal effects. Mazda (and many auto mfgs) does this all the time. It makes the installation much easier and less complex (costs them less), but it still allows them to upsell the audio system as a 6, 8, 10+ speaker system - even if it sounds lousy. The ideal solution is to baffle the speakers - completely isolating the left from the right by building them into some sort of enclosure.

In my case, my NC1 did not come with rear speaker assembly, and when I replaced the OEM non-Bose, I found the rear speakers assembly on EBAY. I soldered new wiring to each speaker, deleting the OEM connectors, and ran the wiring underneath the center console to the replacement head unit. They don't do much but as mentioned, they add a little high freq response that is lost to the wind. These cars are just not designed for high fidelity sound.
