5. Instalace
Proper installation is crucial for optimal performance and safety. If you are not comfortable with electrical wiring, seek professional assistance.
5.1 Montáž Ampdoživotní
- Choose a dry, stable location away from heat sources and direct sunlight.
- Zajistěte dostatečné větrání kolem ampživější.
- Bezpečně namontujte amplifier using the provided hardware to prevent movement during vehicle operation.
5.2 Zapojení kabeláže
Před provedením jakéhokoli připojení odpojte záporný pól baterie vozidla.
- Napájecí kabel: 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.
- Instalace pojistky: Vložte a 20A pojistka into the fuse holder. The 60A fuse included in the RWK82 kit is too large for the KEY2004 and must be replaced.
- Zemnící vodič: 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.
- Kabel pro dálkové zapnutí: 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.
- Vstupní signál:
- 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 ampvysokoúrovňový vstupní svazek zařízení Liferier.
- Dráty reproduktorů: 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:
- Připojení mikrofonu: Plug the Auto-EQ microphone into the dedicated port on the ampživější.
- Umístění mikrofonu: Place the microphone at the primary listening position (e.g., driver's headrest).
- Set Head Unit Volume: Turn your head unit volume to approximately 75% of its maximum.
- 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.
- Počkejte na dokončení: 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).
- Upravit zisk: 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.
- Nastavení přechodu: Select the desired high-pass filter frequency (60Hz, 80Hz, or 120Hz) using the switches on the amplifier, depending on your speaker size and type.
- Volitelné funkce: 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. Obsluha Ampdoživotní
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.
- Zapnutí/vypnutí: The amplifier will turn on and off with your head unit (via remote wire or signal sensing).
- Ovládání hlasitosti: Use your head unit's volume control for overall system volume.
- Úpravy zvuku: 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.
