Where are revv amps located?

Could you please clarify for me the specific context in which you're referring to "revv amps"? Are you inquiring about a technical term related to automotive engineering, such as a type of amplifier used in the electrical system of a vehicle? Or is this a term related to cryptocurrency or finance, perhaps a reference to a specific product or service? Without more context, it's difficult to provide an accurate answer. However, assuming you're asking about a technical component in a vehicle, I would typically expect to find "revv amps" or a similar term referring to a component located in the engine compartment, possibly related to the ignition system or electrical power distribution. Is that along the lines of what you're looking for?
