2. Sicherheitshinweise

Beachten Sie stets die folgenden Sicherheitsvorkehrungen, um Verletzungen oder Schäden am Produkt und am Fahrzeug zu vermeiden:

  • Vor Beginn jeglicher Installation muss der Minuspol der Fahrzeugbatterie abgeklemmt werden.
  • Stellen Sie sicher, dass alle Kabel ordnungsgemäß verlegt und befestigt sind, um Einklemmen oder Beschädigungen zu vermeiden.
  • Use appropriate gauge wiring and fuses as specified. Incorrect fusing can lead to fire or equipment damage.
  • Ziehen Sie einen professionellen Installateur zu Rate, wenn Sie sich bei irgendeinem Teil des Installationsprozesses unsicher sind.
  • Betreiben Sie das amplifier in nassen oder damp Bedingungen.

  • AI-driven DSP: Advanced digital signal processing for sound optimization.
  • FIT2 Technology: Kicker's Fail-Safe Integration Technology for superior input signal compatibility.
  • Start/Stop Vehicle Technology Compatible: Designed to work seamlessly with modern vehicle start/stop systems.
  • Auto 40-Band Equalizer: Automatically adjusts 40 frequency bands for precise sound tuning.
  • Bi-Amp Fähigkeit: Allows for bi-amplification setups (defeasible).
  • Auto Compressor: Dynamic range compression (defeasible).
  • Kicker EQ Preset: Pre-programmed Kicker sound signature (defeasible).
  • Auto Time Alignment: Automatically corrects speaker timing for improved sound staging (defeasible).
  • Auto Level Adjustment: Adjusts levels in Bi-Amp nur im -Modus.
  • Auto Speaker Size Detection: Automatically identifies connected speaker sizes.
  • 24dB Crossovers: Selectable high-pass filters at 60, 80, or 120Hz (defeasible).

5. Installation

Proper installation is crucial for optimal performance and safety. If you are not comfortable with electrical wiring, seek professional assistance.

5.1 Montage der Ampschwerer

  • Choose a dry, stable location away from heat sources and direct sunlight.
  • Sorgen Sie für ausreichende Belüftung um das ampschwerer.
  • Befestigen Sie den amplifier using the provided hardware to prevent movement during vehicle operation.

5.2 Kabelverbindungen

Bevor Sie irgendwelche Verbindungen herstellen, trennen Sie den Minuspol der Fahrzeugbatterie.

  1. Stromkabel: Connect the 8-gauge power cable (from RWK82 kit) directly to the positive terminal of the vehicle's battery. Install the fuse holder within 18 inches (45 cm) of the battery.
  2. Sicherungsinstallation: Fügen Sie ein 20A Sicherung into the fuse holder. The 60A fuse included in the RWK82 kit is too large for the KEY2004 and must be replaced.
  3. Erdungskabel: Connect the 8-gauge ground wire (from RWK82 kit) from the amplifier to a clean, solid metal point on the vehicle chassis. The ground point should be free of paint and corrosion.
  4. Ferneinschaltkabel: Connect the 18-gauge blue remote wire (from RWK82 kit) from the amplifier to the remote turn-on output of your head unit. If your head unit lacks a remote output, the KEY2004 can use DC offset sensing or audio signal sensing for turn-on.
  5. Eingangssignal:
    • RCA (Low-Level) Input: Use the twisted pair RCA cables (from RWK82 kit) to connect the amplifier's RCA inputs to the RCA outputs of your head unit.
    • Speaker Level (High-Level) Input: If your head unit does not have RCA outputs, connect the speaker wires from your head unit directly to the amplifier's high-level input harness.
  6. Lautsprecherkabel: Connect the 16-gauge clear speaker wires (from RWK82 kit) from the amplifier's speaker outputs to your vehicle's speakers. Ensure correct polarity (+ to + and – to –).

6. Setup: Auto-EQ and Initial Configuration

The KEY2004's primary feature is its Auto-EQ capability, which automatically tunes your system. Follow these steps for initial setup:

  1. Mikrofon anschließen: Plug the Auto-EQ microphone into the dedicated port on the ampschwerer.
  2. Platzierung des Mikrofons: Place the microphone at the primary listening position (e.g., driver's headrest).
  3. Set Head Unit Volume: Turn your head unit volume to approximately 75% of its maximum.
  4. Start Auto-EQ: Press and hold the Auto-EQ button on the amplifier (or the remote switch if applicable) until the LED indicator changes. The amplifier will play a series of test tones.
  5. Auf Abschluss warten: Allow the process to complete. This may take several minutes. The amplifier will indicate completion (refer to the specific LED patterns in the full manual).
  6. Verstärkung anpassen: After Auto-EQ, adjust the amplifier's gain controls to match the output of your head unit. Start with the gain at minimum and slowly increase until you hear distortion, then back off slightly.
  7. Crossover-Einstellungen: Select the desired high-pass filter frequency (60Hz, 80Hz, or 120Hz) using the switches on the amplifier, depending on your speaker size and type.
  8. Optionale Funktionen: Enable or disable Bi-Amp Capability, Auto Compressor, Kicker EQ Preset, Auto Time Alignment, and Auto Speaker Size Detection as desired. These are defeasible.

The Auto-EQ process should be performed in a quiet environment with the vehicle's engine off.

7. Bedienung des Ampschwerer

Once installed and set up, the KICKER KEY2004 operates automatically with your vehicle's audio system. The AI-driven DSP continuously works to maintain optimal sound quality based on the initial Auto-EQ calibration.

  • Ein-/Ausschalten: Der amplifier will turn on and off with your head unit (via remote wire or signal sensing).
  • Lautstärkeregelung: Use your head unit's volume control for overall system volume.
  • Toneinstellungen: While the KEY2004 provides automatic optimization, minor adjustments can still be made via your head unit's tone controls if desired. However, significant changes may negate some benefits of the Auto-EQ.

8. Wartung

The KICKER KEY2004 ampDer Verstärker benötigt nur minimalen Wartungsaufwand, um eine langfristige Leistungsfähigkeit zu gewährleisten.

  • Reinigung: Wischen Sie regelmäßig ab ampReinigen Sie die Außenseite des Verstärkers mit einem weichen, trockenen Tuch. Verwenden Sie keine scharfen Chemikalien oder Scheuermittel.
