Hertz UNO Series X-130 5.25" Two-Way Coaxial Speakers User Manual

1. Introduction

The Hertz UNO Series X-130 are 5.25-inch two-way coaxial speakers designed to deliver high-quality audio performance in a vehicle environment. These speakers feature a specially designed tweeter faceplate for optimal off-axis performance, ensuring a linear frequency response. The robust construction, including a water-repellent pressed-paper cone and foam surround, contributes to high sound pressure levels (SPL) and extended low-frequency response, even when powered by an OEM head unit. The 25mm woofer voice coil and high-flux density ferrite magnet provide dynamic power handling for clear, undistorted sound. Their easy-to-install DIN size basket simplifies factory speaker replacement.

3. Setup and Installation

Proper installation is crucial for optimal performance and longevity of your Hertz UNO X-130 speakers. These speakers are designed for easy integration into most vehicle audio systems, particularly as factory speaker replacements due to their standard DIN size basket.

3.1 Unpacking and Inspection

Carefully remove the speakers from their packaging. Inspect both speakers for any signs of physical damage that may have occurred during shipping. Ensure all components are present.

4. Operating Instructions

Once installed, the Hertz UNO X-130 speakers are ready for use. They are designed to provide a rich and dynamic sound experience, even when driven by an OEM head unit.

4.1 Initial Playback

Begin playback at a low volume and gradually increase it. Listen for clear, balanced sound across all frequencies. The speakers are designed for high SPL and extended low-frequency response, providing a full sound profile.

4.2 Audio Settings

Adjust your head unit's equalizer and balance/fader settings to optimize the sound for your vehicle's interior. Due to the tweeter's optimized off-axis performance, these speakers maintain linear frequency response even when not directly aimed at the listener.

4.3 Power Handling

The speakers have a continuous power handling of 40W and a peak power handling of 160W. Avoid exceeding these limits to prevent damage to the speakers. If you notice distortion, reduce the volume immediately.

5. Maintenance

To ensure the longevity and continued performance of your Hertz UNO X-130 speakers, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to gently wipe down the speaker grilles and surrounds. Avoid using harsh chemicals or abrasive cleaners.
• Protection: While the woofer cone is water-repellent, avoid direct exposure to excessive moisture or liquids.
• Environmental Factors: Protect the speakers from extreme temperatures and direct sunlight, which can degrade materials over time.
• Secure Mounting: Periodically check that the speakers are securely mounted and that all connections remain tight.

6. Troubleshooting

If you encounter issues with your Hertz UNO X-130 speakers, refer to the following common troubleshooting steps:

• No Sound from Speaker:
  • Check all wiring connections to ensure they are secure and correctly polarized.
  • Verify that the audio source (head unit) is functioning correctly and outputting sound.
  • Inspect the speaker wire for any cuts or damage.
• Distorted Sound:
  • Reduce the volume level. Distortion often occurs when the amplifier or speakers are overdriven.
  • Check your head unit's equalizer settings. Excessive bass or treble boost can cause distortion.
  • Ensure speaker wires are not shorting out or touching any metal surfaces.
• Weak or Muffled Sound:
  • Check speaker polarity. Incorrect wiring (e.g., positive to negative) can cause sound cancellation.
  • Ensure the speaker grilles are not obstructed.
  • Verify that the speaker is securely mounted and not vibrating against loose panels.

If these steps do not resolve the issue, please contact customer support.
