In terms of mini amplifiers, ESX has been setting the bar for quality and performance very high for years, especially when it comes to very small Class D amplifiers. The QM-TWO amp, which is just the size of the palm of your hand, quickly became the most popular power amplifier in its class and is the perfect solution when things get very tight in the vehicle. With the QM-TWOV2 a new and improved version is now available. While the first QM-TWO with 2 x 80/120 watts RMS was already well fed, the V2 version now boasts an incredible 2 x 105 watts RMS at 4 and 2 x 150 watts RMS at 2 ohms. The increase in performance corresponds to 25% for the same size. The small power plant can even be bridged: Then an impressive 300 watts RMS is available, which is decent even for power-hungry subwoofers. Thanks to the high-level inputs with Error Protection System circuit and the automatic turn-on function, the little wonder is ideal for factory systems.
