Some findings:
I no longer have a hiss sound coming from my speakers when the volume is 0. Previously, my mini amp had been tapped into the power wire of the head unit. Now it has a direct power line to a 15a switch. As such, I am abandoning my project to buy a 5-ch amplifier and to bring a direct 16gauge line into each speaker.
I tapped the front cam into the now unused stereo power wire. It works exactly as intended on the monitor, however two surprises have brought me back to the drawing board:
- The camera has shiny LEDs that are always on, functioning as a central DRL point.
- They're always on even when the car is off.
I'm have to find a different camera and wire. Or maybe put on a switch. I could "flash" people with it.
