Engineered for Data. Defined by Integration.

Our Custom NC OBD2 UltraGauge Center Speaker Mount is the ultimate plug-and-play monitoring solution for the NC MX-5. By utilizing the factory center speaker footprint, this mount houses the popular UltraGauge LCD display seamlessly in your dashboard. It delivers vital, real-time ECU telemetry directly to your line of sight without ugly windshield suction cups or messy exposed wiring.

Real-Time Diagnostics: Your Dashboard Information Hub

Modern engines demand precise monitoring. By mounting the UltraGauge directly in your center speaker slot, you gain instant, high-visibility access to live ECU parameters with digital precision:

Engine Protection: Live, real-time coolant temperature monitoring to track actual engine thermal status with digital precision, catching hot-running situations long before the heavily buffered factory needle begins to climb.
Performance Diagnostics: Real-time RPM, ignition timing, fuel trims (short/long term), and intake air temperatures.
Clear Fault Codes: Instantly read and clear diagnostic trouble codes (DTCs) directly from the unit.

Mechanical Integrity: The “Anti-Teeter” Mounting Design

Just like our standard gauge pod, this specialized version uses our proven Four-Clip Anti-Teeter Design. Engineered directly from the OEM center speaker footprint, the mount replaces your factory speaker cover perfectly. It sits completely level and remains solidly locked in place through high-G cornering, yet can be released and popped out of the dash safely using a plastic trim tool whenever necessary.

Ergonomic & Cable Integration

We didn’t just design a holder; we fully integrated the UltraGauge’s physical connections and onboard features so you don’t lose any functionality or compromise on aesthetics:

Half-Moon Cable Pass-Through: The rear edge of the speaker base plate—closest to the windshield—features a dedicated half-moon clearance slot. This provides an unobstructed path for the bulky, molded UltraGauge connector cable to route straight down into the dash cavity, ensuring the plate sits 100% flush without pinching the harness.
Daylight Sensor Integration: The mount features a precision-placed 3mm sensor aperture aligned perfectly with the UltraGauge’s ambient light sensor. This ensures the unit’s auto-dimming feature operates flawlessly, keeping the screen readable in direct sunlight and comfortably dim during night drives.
Tactile Button Access: Back-mounted buttons are notoriously difficult to reach once a gauge is flush-mounted. We engineered dedicated ergonomic clearance slots directly into the mount face, allowing for easy, unrestricted finger presses of the physical up and down navigation buttons.

Streamlined 15-Minute Installation Workflow

Installing a digital display shouldn’t mean tearing your dashboard apart. We engineered this system to be an incredibly simple 15-minute install:

Pop off your factory center speaker cover using a plastic trim tool.
Pass the flat UltraGauge OBD2 cable down through the half-moon slot at the rear of the base plate and into the center speaker cavity toward the driver’s footwell.
Plug the OBD2 connector into your factory port under the dash, securing excess cable with the supplied heavy-duty zip ties.
Clip the new mount into the dash. Perfect, factory-look integration with zero permanent modifications.

Material Science: High-Grade Thermal Performance

Because this mount sits directly at the base of the windshield, cheap plastics are not an option.

Premium ASA Construction: We manufacture this mount using high-grade Acrylonitrile Styrene Acrylate (ASA).
Extreme Thermal Resistance: ASA is engineered specifically to withstand intense summer cabin heat without warping, sagging, or degrading.
UV Stable: Complete immunity to direct, continuous sunlight and UV exposure.
Paint & Wrap Ready: The high-quality raw ASA surface is ready to run as-shipped for a clean, matte-black motorsport look, or can be custom painted/vinyl-wrapped.

Installation Requirements & Tips

Tools Required: Plastic trim removal tool, OBD2-equipped NC MX-5 (2005–2015).
Pro-Tip: When routing the flat OBD2 cable down through the speaker cavity, drop a small piece of weighted string down first. Tie it to the connector to easily pull the cable down into the footwell before aligning it with the rear half-moon cutout.
Cable Warning: Ensure you route the OBD2 cable completely clear of the steering column and pedal assembly. Use the supplied zip ties to secure the harness safely up and out of the way of your feet.
