Hertz ML Power 5 Mille 5-Channel Amplifier 100W x 4 + 550W

The Hertz ML Power 5 is a Mille-series Class D 5-channel car audio amplifier rated 70 W RMS x 4 plus 380 W RMS x 1 at 4 ohms, and 100 W RMS x 4 plus 550 W RMS x 1 at 2 ohms (14.4 VDC), designed to run a complete four-speaker-plus-subwoofer system from a single chassis in any 12-volt vehicle installation. It is sold as a single amplifier.

Hertz's Advanced D-Class (ADC) topology and a dual-technology heat sink — extrusion plus aluminium die-casting — let the amplifier hold full power continuously in a 349 mm chassis. The filter set is built for one-amp systems: channel banks A and B offer full-range, hi-pass, or band-pass filtering at 12 dB/Oct for front and rear stages, while the dedicated subwoofer channel carries its own 50 - 500 Hz lo-pass at 24 dB/Oct. A 3-channel mode reconfigures the speaker banks to 200 W RMS x 2 at 4 ohms for a high-power front stage plus subwoofer. A status LED reports thermal, overload, and short-circuit protection.

What's Included

Sold individually — one 5-channel amplifier. The HRC BM (Hertz Remote Control Bass Management) subwoofer level remote is optional and sold separately. The ML Power IN input module accepts RCA connections from aftermarket sources and balanced speaker-level connections from factory (OEM) head units; with speaker-level input, the ART (Automatic Remote Turn On-Off) function switches the amplifier without a remote wire.

Fitment / Compatibility

The ML Power 5 is a universal 12-volt car audio amplifier with no vehicle-specific fitment; it installs in any vehicle with a 12-volt electrical system and space for its 349 mm chassis. It is the single-amplifier solution for a full Hertz Mille system — for example an MLK 1650.3 component front stage on bank A, rear speakers on bank B, and an ML 2500.3 subwoofer on the dedicated fifth channel. Its speaker-level input with ART supports unmodified factory head units.

FAQ

Can the Hertz ML Power 5 power a whole car audio system?

Yes. It drives four speaker channels (100 W RMS each at 2 ohms, 70 W at 4 ohms) plus a dedicated subwoofer channel (550 W RMS at 2 ohms, 380 W at 4 ohms) from one chassis.

Is a bass remote included with the ML Power 5?

No. The HRC BM (Hertz Remote Control Bass Management) remote, which adjusts subwoofer level from -20 to +6 dB, is optional and sold separately.

Does the ML Power 5 work with a factory head unit?

Yes. The ML Power IN module's balanced speaker-level input accepts OEM signals, and the ART function turns the amplifier on and off automatically without a remote lead.

What is the difference between the ML Power 5, ML Power 4, and ML Power 1?

The ML Power 5 is the all-in-one: four speaker channels plus a dedicated sub channel. The ML Power 4 is a 4-channel speaker amplifier with more power per channel (250 W x 4 at 2 ohms, bridgeable to 500 W x 2), and the ML Power 1 is the dedicated mono subwoofer amplifier (1000 W RMS at 2 or 1 ohm). Choose the 5 for one-amp simplicity, or the 4 + 1 pair for maximum output.
