With an RMS power of 4×250W at 2Ω, it provides impressive output power suitable for both front and rear speakers and subwoofers. Advanced D-Class (ADC) technology ensures high energy efficiency and excellent sound quality, even in compact dimensions. The integrated variable active switches allow precise adjustment of the frequency response to the respective speaker configurations. Channel A provides an adjustable range of 50Hz to 5kHz, while channel B ranges from 80Hz to 3.3kHz, each with an edge steepness of 12dB/octave. This allows flexible integration into various system designs, including bi-amping setups. The amp has both pre-in and speaker inputs, making it compatible with OEM and aftermarket head units. The ART function (Automatic Remote Turn-On/Off) allows the amplifier to be switched on and off automatically when using the speaker inputs, which simplifies installation and eliminates the need for a separate remote cable. The thermally optimized housing combines extruded and die-cast aluminum to ensure efficient heat dissipation. This allows continuous operation at full power without overheating, which increases the reliability and longevity of the amplifier. With dimensions of 170 × 289 × 46.7 mm and a weight of 2.45 kg, the ML Power 4 can be easily installed in different vehicle types without taking up valuable space. The ergonomic connectors and sophisticated design make it easy to integrate into existing audio systems. Review: Thanks you - I change my car sound system. I had to use before American company amplifier but that’s not very good when I buy to hertz best quality and very high-end, Soundsystem amplifier u need to upgrade ur car amazing amplifier and sound system Review: Ad oggi, a mesi dall'acquisto, si rivela mostruoso e molto stabile. Installato da un professionista mi sta regalando soddisfazioni immense. Amplifico un fronte con Hertz mille pro con woofer tweeter e crossover più coassiali hertz mille pro. Volume altissimo, sound nitido (una volta fatto riscaldare il tutto con qualche utilizzo a bassi-medi volumi per 10minuti) e presto aggiungerò altri altoparlanti per rendere definitivo l'impianto e spingere al massimo delle sue potenzialità questo amplificatore che non scalda troppo né crea problemi alcuno. Perfetto anche per sistemi Spl come 4 diffusori hertz spl show, laddove si potranno raggiungere livelli e qualità altissima di spl. Eccellente per ogni esigeza. ## Features - Radiator with double extrusion, thermally optimised with die cast aluminium ergonomic terminal. - RMS Power 4 Ohm 150Wx4 RMS Power 2 Ohm 250Wx4 - Active crossover with 12 dB / oct power continuously adjustable from 50 to 5K Hz and from 80 to 3.3 K Hz, settable AS lo-pass/high-pass or full range. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Hertz | | Brand | HERTZ | | Product Dimensions | 15 x 10 x 10 cm; 2.45 kg | | Item model number | MLPOWER4 | | Manufacturer part number | ML Power 4 | | Voltage | 1 Volts | | Wattage | 120 watts | | Item Weight | 2.45 kg | ## Product Details - **Item dimensions L x W x H:** 15 x 10 x 10 centimetres - **Voltage:** 1 Volts - **Manufacturer:** Hertz - **Maximum supply voltage:** 14.4 Volts - **Minimum supply voltage:** 1 Volts ## Images ![Hertz ML Power 4 1000W 4-Channel Class-D Amplifier, 4x 150W @ 4 ohms, 4x 250W @ 2 ohms ~ Mille Series ~ - Image 1](https://m.media-amazon.com/images/I/71OeW5KS9tL.jpg) ![Hertz ML Power 4 1000W 4-Channel Class-D Amplifier, 4x 150W @ 4 ohms, 4x 250W @ 2 ohms ~ Mille Series ~ - Image 2](https://m.media-amazon.com/images/I/71vuZS-Y4HL.jpg) ![Hertz ML Power 4 1000W 4-Channel Class-D Amplifier, 4x 150W @ 4 ohms, 4x 250W @ 2 ohms ~ Mille Series ~ - Image 3](https://m.media-amazon.com/images/I/71HS6+OqGVL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Thanks you *by M***T on 18 June 2023* I change my car sound system.
