If you’re restoring a classic car and want to upgrade your dash or rear-deck speaker without changing the look, the Custom Autosound 5″ × 7″ Dual Voice Coil (DVC) speaker is a standout choice. Built specifically for vintage applications, it earns strong marks for fitment, sound quality and value.
Fitment Tailored to Classics
One of the biggest advantages of this speaker is how it integrates into original mounting locations. Instead of removing your dash or cutting new openings, this 5 × 7″ DVC unit replaces the factory speaker in many classic vehicles, especially those that came with a single mono dash speaker. According to the product listing, it offers “stereo input to one speaker” and “140 Watts peak power” while fitting in places designed for smaller, weaker units.
Because it’s tailored for classic applications, installation is simpler and less invasive, which appeals to restorers who want authenticity without sacrificing performance.
Performance & Features
Though still a dash-oriented speaker, the DVC design delivers notable performance upgrades. The listing explains these speakers “provide up to 70% more cone surface area than conventional dual speakers” and “both of your radio’s stereo channels will connect directly to one of our DVC speakers."
Specifically, the 5×7″ version handles peak power up to around 140 Watts and is configured at 4 ohm impedance for drop-in replacement. Owners report improved clarity, more presence in the midrange, and better handling of stereo audio—even in vehicles originally wired for mono output.
One user on a car audio forum commented:
“I’m still using a dash-mounted 5×7″ DVC in my 70’s ride—left and right channels wired into one speaker—and it makes the cabin sound more alive than the old 3.5″ factory unit. Worth the swap.”
Value, Ease of Installation & Practical Use
From a cost-versus-benefit perspective, this speaker hits a sweet spot. With pricing in the ballpark of US $65-75 according to retail listings, you get a major upgrade over stock speaker quality for a modest investment.
Installation is also fairly straightforward: because the unit is built to fit common dash openings, you avoid heavy modification or custom brackets in many cases. That matters in vintage restorations where preserving interior trim is a priority.
Another practical benefit: the dual voice coil layout makes it easier to integrate with modern stereo head units (which output stereo) even though your car may originally have had a mono speaker. This gives you an upgrade path without re-fabricating everything.
Final Thoughts
At Vintage Car Radio, we view the Custom Autosound 5″ × 7″ DVC speaker as a smart, focused upgrade for classic car audio. If your vehicle came with a single dash speaker and you're running a modern head unit or want improved stereo sound without cutting up your interior, this speaker is a very good choice.
Here’s why:
-
Excellent fitment for many original dash applications, less invasive installation
-
Improved sound quality with bigger cone area, better stereo response and decent power handling
-
Great value for the price, making it accessible for many restoration budgets
-
Compatible with modern setups thanks to the dual voice coil design
In short: you can keep your car looking period-correct, retain your dash aesthetics, yet enjoy a real performance upgrade. For many classic car owners who want better sound without sacrificing style, this speaker offers a well-balanced solution.
