1990 Cadillac Brougham built in amp location?

[Scary Guy]

Where the fuck is it? Apparently this is one of the models that the amp is separate from the radio and a pain in the ass to get to. I think I see it but I see a lot of things which could be it. It's probably the obvious thing but it says AC on it. Any advice would be appreciated (pictures even more so.) Thanks!

It could be in the kick panel or against the back seat or up under the dash behind the glove box or under the drivers seat.

From what I've read it's behind the radio or to the lower left of the radio. I see two modules that it could be but I can't figure out which one it is. Logic says it would be the one directly behind the radio, but cars and logic often do not go together lol.
