I've retrofitted the Alpine HiFi kit to my car and I've changed the underseat subs to Logic 7. Everything works only issue is it sounds the same no matter how many times i've coded.

I've followed every single thread on coding the CIC to hifi ($676), I've coded my CAS, my NFRM, and my CIC to hifi. I did FA_Read on the CAS and NFRM and all of them show signs of coding taking place considering it saying "e92_hifi" everywhere instead of e92_stereo. Even when I checked the CIC it said hifi for the cic audio. Problem is everything still sounds boomy and weird..

And when I put the fader to just the rear speakers and crank the volume all the way up, they're still WAY too loud. What's weird is my gong is super quiet, even before I coded, and it still is..

I've heard some people saying "you need an icom" but I've coded my combox retrofit perfectly fine and my CIC accepted that. Is there any module I missed out on coding?

My CIC is on C13 by the way if that helps. build date 09/09

you need remove option 676 and coding only CIC

So it turns out I wired up the mid ranges wrong, the thing was labeled "head unit" but it turns out it plugs into the tweeter and the other side plugged into the head unit cable. It sounds so much better now and my gongs sound normal but I can't tell if the hifi coding worked, the rear speakers are quieter than the fronts but not deafened type of quiet, definitely an improvement for sure but not sure if the hifi coding worked
