Hertz Mille ML Power 4 - 4-channel car amplifier — 120 watts RMS x 4

The Hertz Mille ML Power 4 combines serious power with flexible configurations, making it ideal for audiophiles looking to upgrade their system. This 4-channel amp delivers 120 watts RMS per channel for full-range speakers, 500 watts bridged for subwoofers, or can even be used for bi-amp setups.

For high-powered thrill-seekers

Hertz's Mille ML Power 4 amp combines the versatility of a multi-channel amp with some serious full-range Class-D firepower. This Mille Power Series 4-channel amp can send each of your front and rear speakers 120 watts RMS, which is the kind of power that makes high-performance aftermarket components sound their best. You could also use this amplifier in 3-channel mode to power your front speakers with 120 watts RMS each, while sending 500 watts RMS to a subwoofer. Or, with the amp in bridged 2-channel mode, you could power two subwoofers with 500 watts RMS each. 

Bi-amp a 2-way active system

The ML Power 4's onboard variable crossovers have extraordinarily wide frequency ranges — stretching up to 5000 Hz for Channel-A — so, for instance, you could use the amp to power two tweeters with one pair of channels, and a couple midrange or mid-bass woofers with the other pair.

Fits and works almost anywhere

Hertz engineered this amp using advanced D-Class technology to ensure efficient and reliable performance. The amp's heat sink is built with both extruded and die-cast aluminum to help keep the amp running cool, even when pushed hard. High-level inputs feature Hertz' ART™ (Automatic Remote Turn-on), so this amp can be used to improve the sound in almost any system, even one using the factory radio.
