Hertz MPK 165.3 Review: Mille Pro's Easy-to-Match 4-Ohm Two-Way Set
Updated: Oct 6
The Hertz MPK 165.3 is the 4-ohm, 6.5-inch two-way component set in Hertz's Mille Pro range, pairing the MP 165.3 woofer with the MP 25.3 tweeter (a 29 mm Tetolon dome) through an MPCX 2.3 crossover at 3.5 kHz. Hertz rates it at 110 W continuous and 220 W peak, with a 40 Hz – 22.5 kHz response. Its Indian MRP is ₹49,990, the same as its 3-ohm twin, the MPK 165P.3. Hertz says it designed this set for a wide low-frequency response in cars with no room for a subwoofer, and its 4-ohm load suits almost any amplifier. Check the current price on our MPK 165.3 product page.
Key points
A conventional 4-ohm load, so it works with a head unit to begin with and with practically any car amplifier later.
The system is rated down to 40 Hz, deeper than the 45 Hz of the other Mille Pro two-way set we sell, the MPK 165P.3.
The tweeter comes with an angle support and a flush-mount ring, so it can sit on or in the A-pillar or dash.
We found more owner feedback for it than for the other Mille Pro component sets we sell, mostly positive; one reviewer found it less warm than a rival.

The drivers and the crossover
Hertz gives the MP 165.3 a pure copper voice coil on a polyamide former, which it says combines power handling with low intermodulation distortion on vocals, and a V-cone pulp cone with cotton fibres shaped for linear, wide dispersion through the midrange. A Boundary Free surround widens the midbass, and low-carbon iron plates paired with the ferrite magnet cut distortion at high power.
The MP 25.3 tweeter has a Tetolon fibre soft dome, a neodymium magnet and Hertz's Center Tuning Duct, which lowers its resonance. Its damped rear chamber is sized so it can be crossed over low, and Hertz shaped the faceplate for off-axis use, which matters when a tweeter sits in a pillar and fires across the car.
The MPCX 2.3 hands over at 3.5 kHz with a gentle 6 dB/octave slope on the woofer and 12 dB/octave on the tweeter, plus a two-step tweeter switch. Hertz uses 160 V polyester film capacitors, plus 1 mm pure copper wire inductors on the woofer side to cut losses, and gives the small box a vent grille for heat.
Powering the MPK 165.3
With a 93 dB woofer and a 4-ohm load, the set will run from an aftermarket head unit, a reasonable first step if an amplifier comes later, though a head unit runs out of clean power well before the 110 W continuous rating. A four-channel amplifier giving 50 to 100 W RMS per channel into 4 Ω is the natural partner, and Hertz's DP 4.300 is one we stock.
The 4-ohm load also allows bridging two channels per side on amplifiers rated for 4-ohm bridged loads, within the speakers' rating. For time alignment and full control, the set can also be run actively through a DSP; our guide to setting up a DSP walks through it.
What owners and reviewers say about the Hertz MPK 165.3
We found no professional review, but this set has more owner feedback than the Mille Pro siblings we checked. This is the picture when we checked in October 2026.
UK retailer Four Car Audio lists 16 reviews dated 2017 to 2025, almost all at the top of its scale. Buyers praise the clarity, bass and volume, natural vocals without harshness, and the build quality and mounting parts. One called them a brilliant rear-door upgrade alongside an Audison system; another felt they improved after running in. The single reservation, from 2017, is that they sound less warm than a rival brand's set at a similar price. The page doesn't say how the reviews were collected or verified, and at least one comment is about the fitting shop rather than the speakers.
The product ratings on an eBay listing average 4.9 out of 5 from 7, with five short verified-purchase reviews from 2018 to 2024. One reports much clearer, crisper sound than the speakers replaced, another compares them to older German-made speakers as a compliment, and a third mentions an easy install. Crutchfield's customer review page didn't load for us, and a DIYMobileAudio thread on running it actively with a Helix DSP wouldn't open. Overall, owners are positive on clarity and build, and we found no reliability complaints.
MPK 165.3 vs MPK 165P.3 and other Hertz sets
The MPK 165P.3 costs the same and uses the same tweeter, but has a 3-ohm woofer with a bigger magnet, a 115 W continuous rating and a 4 kHz crossover, against this set's 40 Hz lower limit and 4-ohm load. Choose the 165P.3 for an amplifier rated for 2-ohm loads, and this set for a head unit, a 4-ohm-only amplifier or bridging.
The three-way MPK 163.3 (₹69,990) adds a 70 mm midrange to the same woofer and tweeter; the coaxial MPX 165.3 (₹24,990) avoids separate tweeters. Cheaper Hertz component sets include the Cento Pro CPK 165 (₹29,990) and the Dieci DSK 165.3 (₹10,990). Above it, the Mille Legend MLK 165.3 (₹89,990) also crosses over at 3.5 kHz but adds a 35 mm tweeter, a 150 W continuous rating and a Hi-Contour switch.
Who should buy it, and who shouldn't
Buy the MPK 165.3 if you want a two-way front stage that works with almost any amplifier you have or buy later, your car has little room for a subwoofer, or you plan to start on head-unit power and add an amplifier afterwards.
Look elsewhere if you already own an amplifier rated for 2-ohm loads and want the most output from it (the MPK 165P.3), need a single-hole install (the MPX 165.3), or want a dedicated midrange (the MPK 163.3).
Installation notes for Indian cars
Hertz lists a 63 mm mounting depth for the woofer. Check window-glass clearance and the factory opening, as many installs need an adapter ring, and seal the ring so the back wave can't leak round. Damping the door matters most for midbass, especially without a subwoofer; our sound damping guide shows how.
Use the angle support to surface-mount the tweeter on the A-pillar or dash, or the flush-mount ring in a panel, and start with its switch at 0 dB. The crossover's vent grille is there for heat, so in a car that bakes in summer sun, don't bury it in foam or tape. VA3 Car Studio in Ghaziabad offers professional installation.
Price and where to buy
The MPK 165.3 has an MRP of ₹49,990. VA3 Car Studio often sells below MRP, so check the current offer on our Hertz MPK 165.3 listing. Every set we sell is a genuine Hertz product.
The bottom line
The Hertz MPK 165.3 is the easy-to-match member of the Mille Pro family: a standard 4-ohm load, a woofer Hertz rates to 40 Hz in the system, a flexible tweeter and the largest body of owner feedback we found in the group, mostly positive. One owner found it less warm than a rival, and it rewards an amplifier, but it is a safe, adaptable choice.
Hertz MPK 165.3 FAQ
Is the Hertz MPK 165.3 good without a subwoofer?
Hertz designed it for cars with no room for a subwoofer and rates the system down to 40 Hz. Damp the doors to make the most of that, but expect a subwoofer to add depth that door speakers cannot.
What amplifier suits the MPK 165.3?
A four-channel amplifier giving 50 to 100 W RMS per channel into 4 ohms suits its 110 W continuous rating. Because it is a 4-ohm set, you can also bridge two channels per side on amplifiers rated for 4-ohm bridged loads.
What is the difference between the MPK 165.3 and MPK 165P.3?
The MPK 165P.3 is a 3-ohm version with a different woofer, a 4 kHz crossover and a 115 W continuous rating. The MPK 165.3 is 4 ohms, crosses at 3.5 kHz and is rated to 40 Hz rather than 45 Hz. Both use the same tweeter and cost the same.
