When restoring a classic car, one upgrade that often gets overlooked is the speaker behind the dash. Many factory dash speakers from the 1960s and 1970s were undersized and under-powered. Enter the Custom Autosound Dual dash speaker — a smart upgrade that offers both vintage-friendly fitment and a meaningful sound improvement.
Vintage Fitment & Design
One of the standout advantages of this speaker is how it fits older dash locations designed for smaller or single-coil speakers. According to product specs, it is built for dual dash speaker applications and uses dual voice coils to enable stereo input from a mono location.
That means you can often retain your factory speaker mounting location, grille, and dash trim — a big plus for restorers who want to preserve the original look of the interior. The “dual dash” configuration lets you feed left and right channels into one physical speaker spot — useful in cars that originally only had a single dash speaker or mono radio.
Performance & Sound Quality
This isn’t just a fitment-friendly speaker — it also delivers clear performance upgrades. The manufacturer notes the dual design gives “up to 70% more cone surface area than conventional dual speakers,” resulting in better mid-range response and overall clarity.
In real-world classic-car audio upgrades, owners report that after installing the unit they heard more presence in vocals and instruments, and better dynamics compared to the stock factory speaker. For cabins with limited speaker space and high ambient noise (older cars often have that), any extra cone area and efficiency help.
Installation & Restoration-Friendly Value
From a restoration perspective, this speaker hits several key marks:
-
Drop-in or near drop-in fit, with less fabrication than many modern speaker upgrades.
-
Maintains dash authenticity, which is critical in show cars or original-trim builds.
-
Dual voice coil design adds wiring flexibility, making upgraded head units or stereo outputs easier to integrate.
Because you’re not forced to cut the dash or relocate speakers, you save time and preserve the interior. That matters in builds where the dash, grille, and aesthetic integrity matter as much as sound.
Why It’s Recommended
At Vintage Car Radio, we often suggest this speaker when:
-
Your classic’s dash has a dual dash speaker location and you want to upgrade the sound without altering the dash.
-
You’re running a modern stereo or amplifier and want a speaker capable of handling more than factory output.
-
You want a balanced approach: improved audio clarity and dynamics, while preserving the car’s original interior look.
The dual voice coil design is a particularly smart touch for classic cars. It gives you the ability to hook up stereo output or split channels in one mounting location — a common challenge in older vehicles that came mono or have limited dash space.
Final Thoughts
In short: if your restoration priorities include both style and sound, the Custom Autosound Dual dash speaker is a highly worthy upgrade. It gives you improved audio fidelity, better stereo wiring flexibility, and a fitment that respects your interior. For classic car owners who want better sound without compromising the dash, this speaker hits the sweet spot between authenticity and performance.
