5. Setup and Installation
Proper installation is crucial for the performance and longevity of your amplifier. Follow these general guidelines:
5.1 Mounting Location
- Choose a dry, well-ventilated location away from direct heat sources or moisture.
- Ensure sufficient space around the amplifier for air circulation.
- Securely mount the amplifier using the provided screws to prevent movement during vehicle operation.
5.2 Wiring Connections
Refer to the image below for an overview of the amplifier's connections. Always disconnect the vehicle's battery before making any electrical connections.

- Power (B+): Connect the main power wire from the amplifier to the positive terminal of the vehicle's battery. An in-line fuse (not included) should be installed within 18 inches of the battery.
- Ground (GND): Connect the ground wire from the amplifier to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
- Remote (REM): Connect the remote turn-on wire from the amplifier to the remote output of your head unit. This wire turns the amplifier on and off with your stereo.
- Audio Input (RCA or High Level):
- RCA Input: Use RCA cables to connect the amplifier's RCA inputs to the RCA outputs of your head unit.
- High Level Input: If your head unit does not have RCA outputs, use the provided high-level input harness to connect directly to your head unit's speaker wires.
- Speaker Output: Connect your speakers to the amplifier's speaker output terminals using the provided wafer connectors. Ensure correct polarity (+ to + and - to -) for each speaker. The amplifier is 4 Ohm stereo stable.
6. Operating Instructions
6.1 Gain Adjustment
The gain control adjusts the input sensitivity of the amplifier to match the output level of your head unit. To set the gain:
- Turn the amplifier's gain control to its minimum (fully counter-clockwise) setting.
- Set your head unit's volume to about 75% of its maximum level.
- Slowly increase the amplifier's gain control until you hear distortion, then back it off slightly until the sound is clear.
6.2 Crossover Settings
The amplifier features a 3-way selectable electronic crossover network with High/Flat/Low Pass filter options. This allows you to direct specific frequency ranges to your speakers.
- HIGH PASS: Allows only frequencies above a certain point to pass through, typically used for tweeters or full-range speakers to prevent low bass distortion.
- FLAT (FULL RANGE): Allows all frequencies to pass through, suitable for full-range speakers or if an external crossover is used.
- LOW PASS: Allows only frequencies below a certain point to pass through, typically used for subwoofers.
Select the appropriate setting based on your speaker configuration and desired sound.
7. Maintenance
The Nova AMP-100 amplifier requires minimal maintenance. Follow these guidelines to ensure its longevity:
- Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Ventilation: Ensure that the amplifier's cooling fins remain free of dust and debris to maintain proper heat dissipation.
- Connections: Occasionally check all wiring connections to ensure they are secure and free from corrosion.
8. Troubleshooting
If you experience issues with your amplifier, refer to the table below for common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power / Power LED Off | Blown fuse; Loose power/ground/remote wire; Incorrect wiring. | Check in-line fuse; Verify all power, ground, and remote connections are secure and correct. |
| No Sound Output | Loose speaker wires; Incorrect input connection; Head unit issue; Gain set too low. | Check speaker connections and polarity; Verify RCA or high-level input is connected correctly; Test head unit; Adjust gain. |
| Distorted Sound | Gain set too high; Incorrect crossover setting; Speaker impedance mismatch. | Reduce gain; Adjust crossover settings; Ensure speakers are 4 Ohm stable. |
| Engine Noise / Whining | Poor ground connection; RCA cables routed near power wires; Ground loop. | Ensure solid ground connection; Reroute RCA cables away from power wires; Install a ground loop isolator if necessary. |
