Is there a way to add a DSP to override the stock head unit (Apple Car play model) DSP?

[10thDave]

Is it possible to add something like a processor or something to the HU in the 2017 civic to totally override the car radio's DSP?

Any time I change the DSP from the civics way to DSP-FLAT it sounds so much better, like how it should.

So, is there something I can add on to the radio, going into the 4ch + monoblock wiring to totally ignore the stock HUs DSP? My monoblock is using it's built in line level inputs so I am not using any separate LOC for this setup.

Thanks.

Cost for the Fix-86 is way too expensive for my liking.
