2020 Tacoma AMP Wiring issues

I want to install A sub into my 2020 Toyota Tacoma without the jbl sound package. This is going to require a wire harness plug in for the radio so i'll have RCA ports I believe? The good news is they make a harness with the required connections for a amp, Bad news not for my radio... the 2020's got a new radio with apple car play and a 8inch screen. Has anybody found this harness for the new radio yet or found a suitable way to hook up a amp to the new radio? I haven't found any material online of a solution on TW or the internet. Has anybody put subs in a 2020 Tacoma yet? and if so how did you do it? Sorry if I'm saying anything correct I'm not experienced with wiring nor audio systems. Thanks -Leo

 

Put a full setup in my 4Runner. I think it’s the same radio, or close enough. I used a DSP harness.

 

do you have a link for that?

 

All the info I have is in this thread.
