Hertz MLK 1650.3 Mille Legend 6.5" 2-Way Component Speaker Kit

The Hertz MLK 1650.3 is a Mille Legend series 6.5-inch (165 mm) 2-way component car audio speaker kit that pairs ML 1650.3 woofers with ML 280.3 tweeters through MLCX 2 TW.3 passive crossovers, rated 150 W continuous / 300 W peak power handling at 4 ohms. It is a complete two-channel (left + right) front-stage set for any 12-volt vehicle installation.

The woofers use a pressed-pulp cone with cotton fibres on an Exponential V-cone geometry, a Boundary Free IIR rubber surround, a 36 mm CCAW double-layer voice coil, and an FEA-optimized neodymium magnet in a three-spoke aluminium alloy basket. The 35 mm (1.4 in) tweeters run 28 mm voice coils. The MLCX 2 TW.3 crossover is built for tuners: a bi-amp switch lets you drive woofer and tweeter from separate amplifier channels, Mid-Contour and Hi-Contour selectors move the crossover point between 2.5 kHz (contour on) and 3.5 kHz (contour off), and a three-position tweeter level control trims output +2 / 0 / -2 dB to the car's acoustics.

What's Included

Sold as a complete two-channel kit: two ML 1650.3 6.5-inch woofers with factory die-cast aluminium grilles, two ML 280.3 tweeters with flush-mount hardware, two MLCX 2 TW.3 passive crossovers, and mounting screws and clips. Nothing else is required to build a two-way front stage except an amplifier and wiring.

Fitment / Compatibility

The MLK 1650.3 is a universal 12-volt car audio component set with no vehicle-specific fitment — the woofers install in any 6.5-inch (165 mm) speaker location with at least 69 mm (2.71 in) of mounting depth, and the compact outboard crossovers mount separately. The kit matches Hertz's Mille Power amplifiers; with the crossover's bi-amp switch you can run four amplifier channels (for example a Hertz ML Power 4) into one front stage.

FAQ

Is the Hertz MLK 1650.3 sold as a pair?

Yes. It is a complete two-channel kit: two woofers, two tweeters, and two crossovers — everything for a left and right front stage in one box.

Can the MLK 1650.3 be bi-amped?

Yes. The MLCX 2 TW.3 crossover has a bi-amp switch that lets separate amplifier channels drive the woofer and tweeter of each side independently.

What is the difference between the MLK 1650.3 and the ML 1650.3?

The MLK 1650.3 is the complete two-way kit; the ML 1650.3 is only the 6.5-inch component woofer inside it. The kit adds the ML 280.3 tweeters and the MLCX 2 TW.3 crossovers.

How much mounting depth do the woofers need?

The ML 1650.3 woofers require 69 mm (2.71 in) of mounting depth in a standard 165 mm (6.5 in) speaker location.
