My OEM 400A (9-speaker) 6.5" speakers had poly cones with no tweeters at all - both in the front doors and identically on the rear deck. These may well be the same drivers in the base car? Anyway, my rears had very little treble as well. Now with the Kicker Coax's back there, the rear fill is full range low to high. So, in this case I think that lack of treble from the rear for 300A and 400A cars is due to Ford's speaker selection and not due to lack of a full range signal back there. Having just done my retrofit, you may consider a pair of Kicker coax's for the rear, either another pair for your doors, or consider a dedicated woofer for the lower doors and- perhaps to start - leave the OEM Tweeter in place in the A-pillar. I was surprised to see how close the factory 0.75" tweeter looked to its Kicker replacement. As delivered with the OEM 9-speaker setup, I had my midrange, balance and fade at zero, treble at -2 and bass at +3.Well, it seems no one is interested in helping me upgrade my base 6 speaker stereo, but I learned something today that may be helpful to others.
On my 2017 V6 convertible, the rear speakers get almost no attention from the head unit. Almost 100% of the sound from them is midrange. Changing the treble and bass does very little. Can anyone else confirm if their coupe or convertible does the same thing?
I thought maybe Ford spent all their time tweaking the sound for the 9 & 12 speaker systems and didn't bother adjusting for only one door speaker, but the 9 & 12 are so different from the 6 speaker, that's hard to believe. If anyone is thinking of tapping into the factory head unit for a sub install, I'd recommend tying into the door speakers.
After sitting in the car for an hour tweaking my stereo, I was able to get a good sound with minimal distortion at higher volumes. We'll see how it sounds while driving with the top down, but for now I'm happy enough to put off my speaker upgrade for the time being.
