Hertz DCX 165.3 Dieci 6.5 in 2-Way Coaxial Speakers (Pair)

The Hertz DCX 165.3 is a Dieci line 6.5-inch (165 mm) 2-way coaxial car speaker rated 60 W RMS and 120 W peak power handling at 4 ohms, sold as a pair, with a 15 mm PEI dome tweeter on a neodymium magnet and a built-in crossover. It is a universal 12V replacement for any vehicle with 6.5-inch speaker openings - Hertz's entry-level Dieci series makes it an easy factory-speaker upgrade with no external crossover to mount.

The woofer uses a water-repellent pressed-paper cone with a TPU (thermoplastic polyurethane) surround that damps unwanted resonance even at high excursion, a 25 mm pure-copper voice coil, and a high-density flux ferrite magnet. A DIN-size basket and 64 mm (2.5 in.) mounting depth keep installation friendly in factory door locations.

Compatibility

The DCX 165.3 is a universal 12V coaxial speaker. It fits any car, truck, or SUV with standard 6.5-inch (165 mm) speaker openings, a cutout of about 144 mm (5.7 in.), and at least 64 mm (2.5 in.) of mounting depth. With 93 dB sensitivity and a 4-ohm load it is well suited to factory head-unit power - no amplifier required.

Frequently Asked Questions

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

Yes. It is a standard 165 mm (6.5 in.) DIN-basket coaxial 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 DCX 165.3?

No. With 93 dB sensitivity and a 60 W RMS rating at 4 ohms, the DCX 165.3 is designed to work well directly off a factory or aftermarket head unit; an external amplifier up to about 60 W RMS per channel is optional.

What is included with the DCX 165.3?

Two coaxial speakers with built-in crossovers, sold as a pair. Grilles are optional - the matching Hertz DG 165.3 grille is sold separately.

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

The DCX 165.3 is the coaxial version of the Dieci 6.5-inch speaker - tweeter built onto the woofer for one-hole installation - while the DSK 165.3 is the component kit with separate DT 24.3 tweeters and DX 300 crossovers and a higher 80 W RMS rating.
