1. Hifonics 5-channel power amplifier
Zeus Power ZXR Premium Digital
Not only HiFonics fans know: Those looking for a particularly good and powerful car HiFi amplifier will definitely find what they are looking for in Zeus models. This formula has been true for over 30 years, since the legendary Zeus Series 7 laid the foundation for what makes Zeus amplifiers what they are today: maximum power and performance, along with top-notch sound – in short, the best that Class A/B technology can offer. Experts know that Class A/B amplifiers are excellent but far from compact. For this reason, the HiFonics engineers have completely redesigned the Zeus Power ZXR series as Class D amplifiers. The result is beautiful powerhouses with very slim dimensions – all in the well-known and popular Zeus look. No matter where you look, the ZXR amps are superbly crafted. With an outstanding efficiency of over 90%, they also do not require much power to unleash their full potential. The ZXR series also includes a wired bass remote, allowing levels to be easily adjusted from the driver's seat. Connecting to modern vehicles is more important than ever today. Equipped with the latest EPS high-level input, the speaker signal can be easily tapped from the car radio without causing error messages in the vehicle. All amplifiers are cleverly designed to ensure that the EMC parameters are met, resulting in excellent emission values to avoid interfering with radio reception.

4. ESX Quantum Qs-Two-Iso
With an impressive 2 x 95 watts RMS at 2 Ω, the little Quantum QS-Two is anything but slim. On the contrary, it drives loudspeaker systems with 4, 3, or 2 Ω impedance without difficulty and remains very stable even under critical loads. With a mono bridge output of 190 watts RMS at 4 Ω, it can also elicit a lot of bass from subwoofers. It impresses with its high-end sound: thanks to the huge bandwidth of up to 60,000 Hz and a sensationally low distortion factor of less than 0.007% (THD + N @ 5W), the QS-Two is way ahead.
ESX masters the construction of Class D power amplifiers so well that the QS-Two can achieve a sensational efficiency of up to 90% and is EMC interference-free. The modern technology saves electricity, relieves the vehicle's electrical system, and protects the high-quality components from overheating. Thanks to the high degree of efficiency, no thick power cables need to be pulled. If you want it to be very easy, you can use the QS-Two-ISO, which can be supplied via a pre-assembled ISO cable harness, for example, to connect behind the car radio.
