A simple vista se nota la buena calidad de el amplificador, ya instalado y empezar a calibrar me hizo sonar muy fuerte un set de medios de 3 vías de hertz de 100 whats RMS anteriormente usaba un sound magus pk 700.4 clase d de 100 RMS por canal y creo notar escucharlo más fuerte este Skar aun así siendo de clase A/B que se enfocan más en calidad que en potencia, volvería a comprar amplificadores Skar Audio que si dan potencia real y hasta más de la que muestran en sus especificaciones
