Pioneer GM-DX104 4-Channel Car Amplifier – 400W Max, Efficient Class D, Bridgeable Design, Hi-Res Certified, Gold terminals, Clean Output, Low Interference

Good

I installed the Pioneer GM-DX104 in my 2024 Subaru Forester Sport, and the improvement was far beyond my expectations. The sound quality improved dramatically. Vocals became much clearer, the soundstage opened up, and the door speakers now have much more power and detail. Even at higher volumes, the sound stays clean without distortion. It honestly feels like upgrading to a completely different audio system. Before installing the amplifier, the subwoofer tended to overpower the system, making the midrange and highs sound muddy and less defined. After adding the GM-DX104, the mids and highs became much clearer and more balanced. Because of that, I actually needed to increase the subwoofer level slightly to restore the bass balance I preferred. The wiring was also very straightforward. The semi-transparent yellow wire was used for the power cable, and the semi-transparent brown wire was the ground cable, making the installation easy to understand and reducing the chance of wiring mistakes. I originally considered mounting the amplifier behind the head unit inside the center console because of its compact size. However, after considering heat dissipation, I decided to install it under the front passenger seat where there is much better airflow. It fits perfectly there while allowing plenty of ventilation. This has been the most cost-effective upgrade I've made to my car audio system, and I highly recommend it to anyone looking for a compact 4-channel amplifier.

Amplificatore pazzesco, ha letteralmente trasformato il suono della mia auto! La qualità dell'audio è al top: suono pulitissimo, zero distorsioni anche ad alto volume e bassi potenti che non coprono le voci. Gestisce anche il calore alla perfezione, rimanendo sempre a temperature sicure. ​L'unica nota: per chi lo monta con un'autoradio aftermarket, nella confezione ci vorrebbe un adattatore a 16 pin incluso, perché senza si rischia di impazzire un po' con i collegamenti e i cablaggi. ​A parte questo, è un prodotto definitivo. Consigliatissimo!

Great
