What is this?
 

Found this electronic box mounted on the rear trunk wall of a 3rd gen donor car(by the trunk latch pull down). I am not sure what it is/was. I have no need for it but I'm just curious.

Has a power and ground wire. The ground has a non-factory style terminal. The other wire is like an antenna wire that goes to a few "tuning"? screws, and then a mono RCA style plug into the box. No other wires or inputs/outputs. A search of the numbers on the tag turned up nothing.

I don't know if its a stereo component, an aftermarket antenna, or a lojack type device.

FM/AM signal booster is my guess.

Edit:

Something like this

That what I first thought but all those have an input and an output, this only has one wire other than power/ground.

It's a Flux Capacitor
