About the Hertz DCX 690.3
From our tech experts at CEN
Hertz Dieci series 6x9 inch coaxial pair, with the tweeter in the centre of the woofer, rated at 90w RMS.
Who it suits
Drivers replacing tired factory speakers who want a clear improvement without complication.
Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering rather than guessing. Door treatment matters as much as the speaker itself, and an amplifier will get far more out of these than a head unit can. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Is the Hertz Dieci DCX 690.3 a 2-way or 3-way speaker?
A: It is a 3-way coaxial with a 6x9 inch woofer, a 60 mm midrange and a PEI dome tweeter.
Q: Are grilles included with the DCX 690.3?
A: Yes. Grilles and grille mounting rings are supplied, along with screws, speed clips, the owner's manual and a template on the box.
Q: How deep are the DCX 690.3 speakers?
A: The mounting depth is 98 mm (3.9 in.). Check the clearance under your parcel shelf before fitting.
