Does anyone know where the stereo amp is in a 1995 e350 Club Wagon?

My Chiltons says it's behind the front right cowl trim panel. The diagram isn't very clear in the manual. I'm assuming that panel is on the passenger side, next to the heater core, above the passenger side wheel well? Removed the panel and definitely no amp there.

Thanks in advance!

 

I t does not have one..do you have the stock cassette deck with am /fm ?
With 4 speakers ?
Then there is no amp..You can add one but you need a a new Deck / Head unit...
