Question about Pioneer DEQ-9200 3-Band Car Equalizer
The EQ has two power wires on the back like a head unit. One is constant power, and the other one is ignition/switched power. This normally happens when the installer takes the switched power and applies it to both power leads going into the EQ or head unit. The EQ needs the constant power line run to a 12V source that never turns off. The constant power line is normally yellow, and the switched power line is normally red.

The equalizer has a 3 day backup "battery" in the brain of the unit. It's actually a 5.2v capacitor (.22F) that looks like a watch cell battery. You can order them on digikey, and they have the pos and neg connector already attached. A little fine soldering and it's restored to maintain the memory for the amount of time specified.
As I don't have the exact part number, I wouldn't call it an answer. However, knowing the above, you would need to pull the brain out, open it, and correctly identify the piece anyway.
This worked for me.
