How to add bluetooth (and/or aux input) on a 1990s Honda/Acura CD player, in a way that actually sounds good, so you can play music off your phone on your STOCK 90s CAR STEREO! This video specifically focuses on Honda/Acura CD players from the late 90s found in many different models (Civic, CL, Accord, Integra), but you could adapt this concept to any cd player car stereo of the era.

To activate the CD circuit you need to burn a CD with a silent audio track. Make this track as long as possible, most CDs can hold a track of about 45 minutes. Every time the track ends your audio will cut out for a second as the CD track restarts; this is fine if it only happens every 45 minutes, but if you try use a CD with only a 2 minute silent track, it will be highly annoying. Your CD player will still be fully functional to play normal CDs when your phone is not playing music.
I was inspired by CRXseth who did a similar mod to his vintage Honda cassette deck, and I wanted to adapt it to work on a CD player. Here's his video adding bluetooth to an OEM cassette deck:
