Hertz MPK 163.3 Review: Mille Pro Three-Way Set With a Dedicated Midrange
Updated: Oct 6
The Hertz MPK 163.3 is a 6.5-inch three-way component system from Hertz's Mille Pro range: per side, an MP 165.3 woofer, an MP 70.3 70 mm midrange and an MP 25.3 tweeter with a 29 mm Tetolon dome, tied together by an MPCX 3.3 passive crossover. Hertz rates it at 150 W continuous and 300 W peak into 4 Ω, with 92 dB sensitivity. At ₹69,990 MRP it is the only three-way kit and the most expensive product in our Mille Pro range, with Mille Legend sets above it. It suits owners building a front stage around an amplifier who have a high spot for the midrange. See pricing on our MPK 163.3 product page.
Quick summary
A true three-way: the MPCX 3.3 splits the work at 450 Hz and 5.5 kHz, giving the 70 mm midrange the band in between.
Rated at 150 W continuous into 4 Ω, it is a set for an amplifier, not a head unit.
Placement is the real work: the midrange and tweeter want pods on the A-pillars or dash, not the door.
Owner feedback is sparse but positive, including 5.0 out of 5 from 4 eBay ratings; we found no long-term reports.

How the three-way split changes things
In a two-way set, the 6.5-inch woofer covers bass and most of the vocal range. Here it rolls off from 450 Hz and a dedicated 70 mm driver covers roughly 450 Hz to 5.5 kHz, where most of the detail in voices and instruments lives. The tweeter starts at 5.5 kHz, sparing it the more demanding lower treble. Hertz lists gentle first-order (6 dB/octave) slopes on the woofer and midrange, so the two overlap broadly and where you place them relative to each other matters.
The MP 70.3 midrange is the interesting driver. Hertz uses a symmetrical dual neodymium magnet inside the voice coil, a 20 mm CCAW double-layer coil on a polyamide former with eight decompression holes, a V-cone pulp cone with cotton fibres and a Boundary Free surround, which it says extends the midrange lower. Its rubber magnet cover can be removed where depth is tight. The woofer has a 25 mm pure copper coil, a ferrite magnet and 4 mm of Xmax; the tweeter uses Hertz's Center Tuning Duct.
Amplifier power and tuning
A head unit can't do this set justice. It wants a four-channel amplifier giving roughly 100 to 150 W RMS per channel into 4 Ω, one channel per side through the MPCX 3.3, leaving the other two channels for rear speakers. Hertz's DP 4.300 is one four-channel amplifier we stock, though at 60 W per channel into 4 Ω it falls below that range. Start with both level switches at 0 dB; raise the midrange or tweeter only if the car's trim and glass make the sound dull.
The other route is active: skip the passive crossovers and drive the three drivers from six channels of a DSP amplifier. You gain time alignment and control of the crossover points, but protecting the tweeter becomes your job, so it needs a careful tune. Our guide to setting up a DSP in your car explains the steps.
What owners and reviewers say about the Hertz MPK 163.3
We found no professional review; this is the owner feedback we found when we checked in October 2026.
The eBay product page shows 5.0 out of 5 from 4 ratings, with four short verified-purchase reviews dated 2018 to 2026. One says it sounds sweet on good amplification, another found it far better than the factory Bose speakers it replaced, a third praises the sound, and the fourth reports it performing well and perhaps improving with use.
On the Mustang6G forums, a thread running from 2022 to 2025 starts with a Mustang owner choosing between this set and the MPX 165.3, worried about the midrange's mounting depth. An MPK 163.3 owner replied that the set fitted fine with aftermarket adapters, and another member said it should sound very good if set up correctly. That is a US car, so take it as a reminder to check depth, not as fitment advice.
Crutchfield has a customer review page and CorvetteForum a thread comparing it with Morel's Virtus 603, but neither loaded for us. We found no complaints, but four ratings and one fitment report are not a consensus; if you run this set, we would welcome your notes.
MPK 163.3 vs MPK 165.3 and Mille Legend
The two-way MPK 165.3 (₹49,990 MRP) uses the same MP 165.3 woofer and MP 25.3 tweeter with the two-way MPCX 2.3. The MPK 163.3 adds the midrange, raises the continuous rating from 110 W to 150 W and moves the tweeter's crossover from 3.5 kHz up to 5.5 kHz; both list 40 Hz – 22.5 kHz. The extra ₹20,000 is mainly worth paying if you can mount that midrange well.
Adding the MP 70.3 (₹29,990 MRP) to an MPK 165.3 would cost more than the MPK 163.3 and still leave you with a two-way crossover, so for a passive three-way the kit is the cheaper route. If you would rather stay two-way and move up a range, the Mille Legend MLK 165.3 (₹89,990) has the same 150 W continuous rating, a 35 mm tweeter and a response listed to 25 kHz.
Who should buy it, and who shouldn't
Buy the MPK 163.3 if you are building a front stage around a good four-channel amplifier or a DSP, you care most about vocals and instruments, and you are willing to have A-pillar or dash pods made for the midrange and tweeter.
Look elsewhere if you plan to run the speakers from a head unit, or your car offers no sensible high spot for a 70 mm driver. The MPK 165.3 is easier to place, and the coaxial MPX 165.3 simpler still.
Installation notes for Indian cars
The woofers go in the doors, where Hertz lists a 63 mm mounting depth for the MP 165.3. Check window-glass clearance and the factory opening, as many installs need an adapter ring, and damp the door skin while the panel is off; our sound damping guide explains the method.
The midrange and tweeter belong high and close together, usually in custom A-pillar pods or dash-corner locations; our article on aluminium pods for three-way systems shows the approach. Hertz includes an angle support, flush-mount ring and watchband for the tweeters. Mount the 0.43 kg crossovers under the seats or in the kick panels, away from water inside the doors.

Price and where to buy
The MPK 163.3 carries an MRP of ₹69,990. VA3 Car Studio often sells below MRP, so check the current offer on our Hertz MPK 163.3 listing. Every set we sell is a genuine Hertz product.
The bottom line
The Hertz MPK 163.3 is Mille Pro's most ambitious set: a dedicated neodymium midrange, a three-way crossover with level controls and a 150 W continuous rating. It needs an amplifier and careful placement, and owner feedback is sparse. With pods and proper power, it is the logical step beyond a two-way front stage.
Hertz MPK 163.3 FAQ
Does the Hertz MPK 163.3 need an amplifier?
In practice, yes. It is rated at 150 W continuous, far more than a head unit delivers. A four-channel amplifier giving roughly 100 to 150 W RMS per channel into 4 ohms suits it, or a DSP amplifier if you want to run it actively.
Where should the MPK 163.3 midrange be mounted?
High and close to the tweeter, usually in A-pillar pods or dash corners, with the woofers in the doors. Its rubber magnet cover can be removed where depth is tight, but ask us to check your car before planning pods.
Can I add the MP 70.3 to an MPK 165.3 instead?
You can, but it costs more than the MPK 163.3, and the MPK 165.3's two-way crossover has no midrange output, so you would need a separate three-way crossover or an active DSP setup. For a passive three-way, the MPK 163.3 with its MPCX 3.3 is the cheaper route.
