Amplifier Installation? 2017 GLA250 non-HK

Dany, please post in English. If I can translate so can you. Thanks.

It’s far easier to install an amp in a 250 with the basic audio system as room for same beneath the cargo floor. A number of folks here have done so.

excuse me Hi, greetings to all, I'm Dany from Argentina. Has anyone installed an amplifier in a 2017 GLA250?

What existing audio system do you have?

An example of work done by another member (easily searched):

hello, the audio system is not harman kardon. it sounds very bad

Does anyone know where I can see how the audio system is configured?

The service/shop manual for the vehicle audio system is always the best resource.

ref: (generally the same for GLA250) GLA45 AMG Service Instructions

Welcome, yes it has been done. Manufacturers like Audison and Audiotec-Fischer make direct-fit wiring so you can easily install an amplifier inline with your original radio unit and control bass, treble, and mid from the on-screen controls. No modifications needed. If you wish, you can then upgrade speakers with their direct-fitment lineup as well.

I am the author of the second link (Audio upgrade guides), you can hopefully find what you need there.
