Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Apocalypse AP-M61SE 6.5-inch Midrange Car Audio Speakers. Please read this manual thoroughly before installation and use to ensure optimal performance and longevity of your speakers.
Safety Information
Always observe the following safety precautions:
- Disconnect the vehicle's battery negative terminal before starting any electrical work to prevent short circuits.
- Ensure all wiring is properly insulated to prevent electrical shorts and damage to your vehicle's electrical system or audio components.
- Use appropriate gauge wiring for power and speaker connections to handle the speaker's power requirements.
- Avoid installing speakers in locations that obstruct vehicle operation or safety features.
- Consult a professional car audio installer if you are unsure about any part of the installation process.
- Do not operate the speakers at excessively high volumes for prolonged periods, as this can cause hearing damage and speaker damage.

Setup and Installation
Proper installation is crucial for optimal sound quality and speaker longevity. Follow these guidelines:
1. Mounting Location
Select a suitable mounting location in your vehicle that provides adequate space and structural integrity. The speakers are designed for flush mounting.
Note: Ensure the mounting surface is flat and free from obstructions. Consider the speaker's mounting depth and overall diameter.
2. Preparing the Mounting Hole
Carefully measure and mark the cutout area. The front mount baffle cutout diameter is 5.86 inches (149.5mm). The mounting depth is 2.83 inches (72.5mm). Use appropriate tools to create a clean and precise opening.

3. Wiring Connections
Connect the speaker terminals to your amplifier or head unit. Pay close attention to polarity (positive to positive, negative to negative) to ensure correct phase and optimal sound reproduction. The nominal impedance of these speakers is 4 Ohm.
- Positive (+) Terminal: Connect to the amplifier's positive output.
- Negative (-) Terminal: Connect to the amplifier's negative output.
Important: These speakers have a MAX Power Handling of 260 Watts and an RMS Power Handling of 130 Watts. Ensure your amplifier's output matches these specifications to prevent damage.

4. Securing the Speakers
Once wired, carefully place the speakers into the prepared openings and secure them using appropriate screws. Do not overtighten, as this can damage the speaker frame.
Operating Instructions
After installation, follow these steps for initial operation:
- Initial Power-Up: Reconnect the vehicle's battery. Turn on your car audio system.
- Volume Adjustment: Start with the volume at its lowest setting and gradually increase it to a comfortable listening level.
- Audio Settings: Adjust your head unit's or amplifier's equalizer and crossover settings. For midrange speakers, a recommended frequency response is 100Hz ~ 15.5KHz. It is advisable to use a high-pass filter to prevent low frequencies from reaching the midrange speakers, which can cause distortion and damage.
- Break-in Period: Allow a break-in period of several hours of normal listening to allow the speaker components to loosen and achieve optimal performance.
Maintenance
To ensure the longevity and performance of your speakers, follow these maintenance tips:
- Cleaning: Use a soft, dry cloth to gently wipe the speaker cones and surrounds. Avoid using harsh chemicals or excessive moisture.
- Inspection: Periodically check speaker connections for tightness and ensure no wires are frayed or exposed.
- Environmental Factors: Protect speakers from extreme temperatures, direct sunlight, and excessive moisture.
Troubleshooting
If you encounter issues with your speakers, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound | Loose wiring connection, incorrect polarity, amplifier off/faulty, head unit issue. | Check all wiring connections for tightness and correct polarity. Verify amplifier and head unit are powered on and functioning correctly. |
| Distorted Sound | Volume too high, incorrect amplifier gain settings, improper crossover settings, damaged speaker. | Reduce volume. Adjust amplifier gain to prevent clipping. Ensure proper high-pass filter is applied. Inspect speaker for visible damage. |
| Weak or Muffled Sound | Incorrect polarity, phase issues, inadequate power. | Double-check wiring polarity. Ensure speakers are receiving sufficient power from the amplifier. |
If the problem persists after attempting these solutions, consult a qualified car audio technician.
