2020 12 speaker system. question (sub)

[ICU812]

Hello, my 2020 has the 12 speaker set up with sub. Problem is some media be it radio channel or a morning talk radio show bewteen music, the bass will be fine on some and other station or even same station but different song, will be over the top.
On my other vehicles I had a sub amp volume control near driver, To adjust as needed without having to go into the radio eq settings.
Is the factory sub amp in the sub? I would like to add that type control .
I am assuming if the sub has the amp inside the box, the feed is mono, and not both channels.
The music I play is everything from the 60's rock to today, and some 80's synth and dance music and a little 80's rap. so the pre digital recording the eq of the recording has less bass db than what today can get away with, that a record player could not. This makes DOKKEN bass needing big boosting, but other later recording needing much less. And going into the settings to then click sound then the eq bass is a r.p.i.t.a.
A sub amp volume control would fix this. BUT I need to know if the sub has it's own amp, where it is, and if the feed to it is line level or speaker level, mono, or both L&R and the sub amp deals with that.
Example, I put in rush moving pictures and set the bass and after that put in Rush live in Rio and the bass was over powering the rest of the music

In this case a bass control knob is only a band aid for mediocre recordings.
If at the same setting with one song the bass is overbearing and with another there is no bass (Metallica - And justice for all.... <cough>) then it's the recording and the audio system should play it exactly like it was recorded, the one recording with overbearing bass and the other with virtually no bass.
Afaik the stock subamps have no input for a bass control knob either.

This is also a problem with a cheap factory subwoofer tuned for maximum output at a very narrow range of bass frequencies. You get overwhelming monotone bass in some recordings that happen to play within that frequency band and then bass sounds like it is completely lacking from other recordings where those frequencies are slightly out of the subwoofers peaked response band.

There’s an old adage in car stereo which goes “garbage in garbage out“. If you really want to enhance your base response you need to tap the signal coming out of the head unit before it gets processed by the stock amp and go from there. The OEM programming lets the base roll off as the volumes get higher and it is already a base heavy signal as is.
