What Classic Car Enthusiasts Are Saying
For restorers and hot-rod builders who want modern audio performance hidden in classic styling, the Secret Audio line from Custom Autosound hits the mark. Owners consistently praise the system’s stealth installation, connectivity, and functionality. Here’s a breakdown of what reviewers want you to know—and why the Secret Audio is earning strong reviews in the classic car audio space.
Discreet Installation, Big Performance
One of the most frequent compliments is how the Secret Audio system disappears into the vehicle. Many users love that the “brains” of the system can be hidden away—under a seat, behind the dash, or in the trunk—while a simple remote or flush mount display controls the unit. As one listing puts it: “Works great, out of sight from thieves.”
On the performance side, reviewers highlight the specs: 200 watts (50 × 4), four-channel RCA pre-outs, subwoofer output, Bluetooth streaming, USB/MP3 playback, and more. One install video notes that the system includes all necessary wiring and remote controls, making it ideal for vehicles where a traditional dash radio simply won’t fit.
Real-World Feedback from Enthusiasts
In user forums and product review pages, several themes emerge:
-
Stealthy look: Many say the SecretAudio lets them keep their original dash radio face or aesthetics intact while getting modern sound.
-
Versatility: Because the head unit is hidden, you’re free to mount everything in tight or unconventional spaces—perfect for roadsters, customs, or show cars.
-
Modern features: Bluetooth streaming, USB playback, full RCA outputs and sub integration all earn positive mention.
-
Overall value: One user remark it’s “first class” and indicates they’d buy it again.
Why It Works for Classic-Car Builds
The Secret Audio system is tailored for cars where originality or aesthetics matter—but functionality can’t be sacrificed. Here’s why it stands out:
-
Original dash remains intact: You don’t need to cut or replace your factory radio bezel.
-
Hidden unit: means fewer visible modern controls messing up your antique interior.
-
Expansion friendly: With RCA pre-outs and sub output, you can pair the system with bigger amplifiers or speaker upgrades later.
-
Compact form factor: Makes it easier to fit in cramped cabins, behind boxes, or under seats—ideal when dash space is limited.
Notes & Balanced Perspective
While the reviews are overwhelmingly positive, savvy buyers do note a few things:
-
Proper wiring and grounding matter. Because the brain unit is hidden, ensure wiring is clean and fused to avoid interference or overload.
-
Because the dash face or remote control is simplified, setup may require a moment of learning if you’re used to traditional radios.
-
As with all audio gear, performance still depends on your speaker setup, enclosure quality, and wiring—SecretAudio provides the foundation, but system tuning still counts.

If you’re restoring a classic car and want serious audio capability without sacrificing dash authenticity, the Secret Audio from Custom Autosound consistently earns high marks. It delivers modern connectivity, hidden installation, and smart expansion options—all while letting your car retain its vintage look.
