AudioControl Amp does not correct the Toyota all-pass filter?

Hello,

I have two AudioControl amplifiers (LC-1.800 & LC-4.800) from my previous car that I'd like to install. I'm keeping the factory head unit (non-JBL) but replacing the speakers (Infinity Kappa throughout & Alpine Sub). I read in a post AudioControl doesn't correct the All-Pass filter in Toyota's. Has anyone heard of this? Crutchfield said they had not heard this before, but suggested an Alpine PXE-C60 DSP if it is the case?

Any guidance is appreciated.

Also, are the factory speaker wires 16 gauge?

Head Unit:
I would like to keep the stock head unit. I realize doing this will require a DSP/LOC to correct the signal coming off the head unit. I originally looked at the AudioControl brand, but was moved away from it after I found that didn't correct the Toyota all-pass filter that is in place. Because of this, additional research led me to the Helix brand. It seems Helix is the way to go to correct the Toyota signal. Can someone recommend a good model for this task? I'm also unsure if I should go DSP/AMP combo. If there is another recommended make for Toyota factory head unit integration, please let me know.
