Hertz Mille Pro MPK 165.3 - 16.5 cm 2-Way Front System for Powerful Bass without a Subwoofer
The Hertz Mille Pro MPK 165.3 is a 6.5-inch component front system that delivers a broad and controlled bass range in vehicles without a subwoofer option. The MP 165.3 woofer utilizes V-Cone and Boundary Free Surround technology for clean dispersion and high sound pressure in a compact size. The passive 2-way crossover MPCX 2.3 ensures a natural transition to the MP 25.3 tweeter and calibrates its level. A 1mm copper coil with low parasitic resistance in the crossover increases the system's efficiency. At Carhifi.shop, you can get the set as a harmonious solution for near-OEM integration with a noticeable upgrade in the mid-range and bass.
