I’m considering grabbing one of these devices for the audio amplifier.

It’s easily found on EBay, Amazon, and google searches as:

“TDA7850 50W 4 CH 12V Car Audio Amplifier Board DIY Kit”

However, it’s a fixed gain amp, so on the plus side everything is controlled by the computer.

The downside is that every bit of noise will be amplified too.
