איידער איר מאַכט קיין קאַנעקשאַנז, דיסקאַנעקט די נעגאַטיוו באַטעריע וואָקזאַל פון די פאָרמיטל.

  1. מאַכט דראָט: 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. פיוס ינסטאַלירונג: לייג אריין א 20 א קאָריק into the fuse holder. The 60A fuse included in the RWK82 kit is too large for the KEY2004 and must be replaced.
  3. ערד דראָט: 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. Remote Turn-On Wire: 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. אַרייַנשרייַב סיגנאַל:
    • 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. רעדנער ווירעס: 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. פאַרבינדן מיקראָפאָן: Plug the Auto-EQ microphone into the dedicated port on the ampליפער.
  2. מיקראָפאָן אָרט: 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. וואַרטן פֿאַר קאַמפּלישאַן: 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. סטרויערן געווינס: 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. קראָססאָווער סעטטינגס: 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. אָפּטיאָנאַל פֿעיִקייטן: 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. אַפּערייטינג די Ampליפער

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.

  • מאַכט אויף / אַוועק: די amplifier will turn on and off with your head unit (via remote wire or signal sensing).
  • באַנד קאָנטראָל: Use your head unit's volume control for overall system volume.
  • געזונט אַדזשאַסטמאַנץ: 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.
