Hertz MPK 165.3 Component Mille Pro 6.5" Speaker System for Harley

$619.00 $549.99

A Spectacular Speaker System for Harley Applications

We like this speaker system a lot. The acoustic energy that these speakers are capable of delivering is spectacular. One of the best-sounding speaker sets we have ever tested. 

The MPK 165.3 speakers system has been designed to ensure a wide low-frequency response. The bass response of this speaker is particularly spectacular. Thanks to the V-cone® and Boundary Free Surround technologies the MPK 165.3 woofer boasts outstanding dispersion features and generates high SPL with compact dimensions. The dedicated crossover MPCX 2.3 has been designed to exploit the wide extension of the MPK 165.3 woofers, ensuring a natural transition towards the MP 25.3 tweeter, for maximum natural acoustic emission. The 1mm low parasitic resistance copper filter coil of the woofer maximizes its efficiency. The MPCX 2.3 crossover features a tweeter level (0/+2 dB) to calibrate the MP 25.3 acoustic emission level comparing it to the woofer one.

Crossover Fitment:

Hetz MPK165.3 Crossover Modification for Easier FitmentThis speaker kit comes with a passive crossover that can be modified for easier fitment in the fairing. Batwing fairings in particular do not have enough room in them for both an amplifier and the crossovers that come with these speakers. So we offer a service where we modify the crossovers in order to reduce the size and make them a drop-in fit. We also pre-wire them while we are at it to make them completely plug and play.

Note: this modification is not required for '13 and older bikes. 


We have found the MPK165.3 speaker system to be an outstanding performer in Harley applications. These speakers are capable of unusually high output, low-frequency response (bass), and have a very high efficiency compared to most any other component speaker.  

Amplifier Power

These speakers perform well with 75 watts or more per channel.
