Hertz DSK 165.3 Dieci 6.5 in 2-Way Component Speaker Kit

The Hertz DSK 165.3 is a Dieci line 6.5-inch (165 mm) 2-way component car speaker kit rated 80 W RMS and 160 W peak power handling at 4 ohms, sold as a complete two-speaker set: two DV 165.3 woofers, two DT 24.3 tweeters, and two DX 300 crossovers. It is a universal 12V front-stage upgrade for any vehicle with 6.5-inch door openings and a dash, sail-panel, or A-pillar spot for the compact separate tweeters - no vehicle-specific fitment.

The DV 165.3 woofer uses Hertz's V-cone profile in water-repellent pressed paper for strong off-axis response and detailed mid-high output, with a TPU (thermoplastic polyurethane) surround that stays linear and damps resonance at high excursion, a 25 mm pure-copper voice coil, and a high-density flux ferrite magnet. The DT 24.3 tweeter pairs a 24 mm PEI dome with a high-energy neodymium magnet and an annular acoustic lens, and ships with mounting accessories for surface or flush installation.

What's Included

• 2 x DV 165.3 6.5-inch (165 mm) woofers
• 2 x DT 24.3 tweeters (24 mm PEI dome, neodymium magnet)
• 2 x DX 300 compact crossovers (tweeter high-pass, 3.5 kHz at 12 dB/octave)
• Tweeter mounting accessories for external or embedded (flush) mounting

Sold as a complete kit for a left and right front stage. Matching grilles are not guaranteed in the box - Hertz lists the 6.5-inch Dieci grille as an optional accessory.

Compatibility

The DSK 165.3 is a universal 12V component system. The DIN-basket woofers fit any vehicle with standard 6.5-inch (165 mm) openings, a ~144 mm (5.7 in.) cutout, and at least 64 mm (2.5 in.) of mounting depth; the compact 34 mm tweeters mount almost anywhere with the included accessories. With 93 dB sensitivity and a 4-ohm load, it works on head-unit power or with an amplifier up to about 80 W RMS per channel.

Frequently Asked Questions

Will the Hertz DSK 165.3 fit my 6.5-inch speaker openings?

Yes. The DV 165.3 woofer is a standard 165 mm (6.5 in.) DIN-basket format with a 144 mm (5.7 in.) cutout and 64 mm (2.5 in.) mounting depth, so it drops into most factory 6.5-inch door locations.

Do I need an amplifier for the DSK 165.3?

No - with 93 dB sensitivity and an 80 W RMS rating at 4 ohms it performs well straight off a head unit; an external amplifier up to about 80 W RMS per channel is optional for maximum output.

What is included with the DSK 165.3?

Two DV 165.3 woofers, two DT 24.3 tweeters, two DX 300 crossovers, and tweeter mounting accessories for surface or flush installation - a complete two-speaker kit.

What is the difference between the Hertz DSK 165.3 and DCX 165.3?

The DSK 165.3 is the Dieci component kit - separate 24 mm tweeters and DX 300 crossovers, rated 80 W RMS - while the DCX 165.3 is the Dieci coaxial with the tweeter built onto the woofer, rated 60 W RMS.
