About the Hertz MP 165.3
From our tech experts at CEN
The Hertz Mille Pro MP 165.3 is a pair of 6.5 inch (165 mm) midbass woofers, not subwoofers. They handle 90 W RMS and 180 W peak at 4 ohms, cover 40 Hz to 5 kHz, and use a V-cone pressed pulp cone with cotton fibres, a Boundary Free surround and a ferrite magnet.
Who it suits
Component and active door builds that want strong midbass, even in cars without room for a subwoofer. For use with 2 ohm stable amplifiers, the MP 165P.3 is the 3 ohm, 100 W RMS version.
Our tech experts advise
As woofers only, they need a low-pass from a crossover or DSP and a separate tweeter such as the MP 25.3. They have ±7 mm of mechanical excursion, so solid mounting and door deadening pay off. Installation is priced per vehicle, so get in touch.

Frequently Asked Questions
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What size enclosure does this subwoofer need?
A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Sealed or ported enclosure - which should I choose?
A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
Q: How much power can the Hertz MP 165.3 handle?
A: Each woofer is rated at 90W continuous and 180W peak power handling, at 4 ohms impedance.
Q: Is the Hertz MP 165.3 a subwoofer or a door woofer?
A: It is a 6.5-inch (165mm) woofer with a 40Hz to 5kHz frequency response. Its V-cone and Boundary Free Surround give wide low-frequency response from a compact size, which helps in cars with no space for a subwoofer.
Q: Are grilles included with the MP 165.3?
A: Yes. An optional full protection metal mesh grille and a mineral powder coated inner grille are included for several install combinations.
