The single knob design provides intuitive control over one or two mono-channel amplifiers.
5. Setup and Installation
Proper installation is crucial for optimal performance and safety. It is recommended to have this system installed by a qualified professional if you are not experienced with car audio wiring.
5.1. General Wiring Guidelines
- Disconnect Battery: Always disconnect the negative terminal of your vehicle's battery before starting any wiring.
- Mounting Location: Choose a secure, dry, and well-ventilated location for the amplifier. For motorcycle applications, ensure it fits securely within the fairing.
- Wire Routing: Route power, ground, and signal cables separately to minimize noise interference. Avoid sharp edges and moving parts.
- Fusing: Install the provided 100 Amp fuse holder within 18 inches of the battery's positive terminal.
5.2. Amplifier Wiring Steps
- Power Connection: Connect the 17 ft 4 AWG blue power wire from the fuse holder (connected to the battery's positive terminal) to the amplifier's +12V terminal.
- Ground Connection: Connect the 4 ft 4 AWG gray ground wire from the amplifier's GND terminal to a clean, bare metal chassis point on the vehicle. Use the self-tapping bolt and washer to ensure a secure connection.
- Remote Turn-On: Connect the 17 ft 16 gauge remote wire from your head unit's remote output to the amplifier's REM terminal. This wire turns the amplifier on and off with your head unit.
- Signal Input: Use the 16.4 ft KI RCAs to connect the head unit's RCA outputs to the amplifier's RCA inputs. If your head unit does not have RCA outputs, the amplifier's high-level input can be used (refer to the amplifier's specific wiring diagram for high-level input).
- Speaker Output: Connect your subwoofer(s) to the amplifier's speaker output terminals using the 12 ft Q Series 12 AWG speaker wire. Ensure correct polarity (+ to + and - to -).
5.3. Dual Bass Remote Installation
Mount the dual bass remote in a convenient location within reach of the driver. Connect the remote to the amplifier's remote input jack (typically a 3.5mm input) using the provided cable. This remote allows for real-time adjustment of bass levels.
6. Operating Instructions
6.1. Initial Power-Up
After completing all wiring and double-checking connections, reconnect the vehicle's battery. Turn on your head unit. The amplifier should power on automatically via the remote turn-on wire.
6.2. Adjusting Amplifier Settings
The KPX500.1 amplifier features several adjustable controls to fine-tune your audio system:
- Gain Control: Adjust the gain to match the output voltage of your head unit. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly.
- Crossover: Set the low-pass filter (LPF) to the recommended frequency for your subwoofer(s). This ensures only low frequencies are sent to the subwoofer.
- Subsonic Filter: Adjust the subsonic filter to protect your subwoofer from playing frequencies below its resonant frequency, which can cause damage.
- KickEQ Bass Boost: Use this control to add a boost to specific bass frequencies if desired. Use sparingly to avoid distortion.
6.3. Using the Dual Bass Remote
The dual bass remote allows you to conveniently adjust the output level of your connected mono amplifier(s) or powered subwoofer(s) from your listening position. Rotate the knob clockwise to increase bass output and counter-clockwise to decrease it.
7. Maintenance
The KICKER KPX500.1 amplifier is designed for durability and weather resistance, requiring minimal maintenance.
- Cleaning: Periodically wipe the amplifier and remote with a soft, dry cloth to remove dust and dirt. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Regularly check all wiring connections for tightness and signs of corrosion or damage. Ensure the fuse holder is secure and the fuse is intact.
- Ventilation: Ensure the amplifier's cooling fins are free from obstructions to allow for proper heat dissipation.
8. Troubleshooting
If you experience issues with your KICKER KPX500.1 system, refer to the following common problems and solutions:
8.1. No Power/Amplifier Not Turning On
- Check Fuse: Verify the 100 Amp fuse in the fuse holder is not blown. Replace if necessary.
- Power/Ground Connections: Ensure the +12V power and GND wires are securely connected and have good contact.
- Remote Turn-On: Check that the remote wire is connected to a switched 12V source from your head unit and is receiving power when the head unit is on.
- Battery Voltage: Ensure your vehicle's battery has sufficient charge.
8.2. No Sound Output
- RCA/Signal Input: Verify RCA cables are securely connected at both the head unit and amplifier. Test with another audio source if possible.
- Speaker Connections: Check speaker wire connections at both the amplifier and subwoofer for correct polarity and secure contact.
- Head Unit Settings: Ensure the head unit's volume is up and the correct audio source is selected.
- Amplifier Gain: Ensure the amplifier's gain is not set to minimum.
8.3. Distorted Sound
- Gain Setting: Reduce the amplifier's gain. If the gain is set too high, it can cause distortion.
- Crossover/Subsonic Filter: Adjust these settings to ensure the subwoofer is only playing appropriate frequencies.
- Speaker Impedance: Verify that the connected subwoofer's impedance is within the amplifier's supported range (1-4 Ohm).
- Power Supply: Ensure the amplifier is receiving stable power. Low voltage can cause distortion.
8.4. Bass Remote Not Functioning
- Cable Connection: Ensure the remote cable is securely plugged into both the remote and the amplifier's input jack.
- Compatibility: Confirm the amplifier supports the 3.5mm remote input.
