- 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 Kapasite: 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 mòd sèlman.
- Auto Speaker Size Detection: Automatically identifies connected speaker sizes.
- 24dB Crossovers: Selectable high-pass filters at 60, 80, or 120Hz (defeasible).

5. Enstalasyon
Proper installation is crucial for optimal performance and safety. If you are not comfortable with electrical wiring, seek professional assistance.
5.1 Monte a Amplifier
- Choose a dry, stable location away from heat sources and direct sunlight.
- Asire bon jan vantilasyon alantou an amplifier.
- Byen monte a amplifier using the provided hardware to prevent movement during vehicle operation.
5.2 Koneksyon fil elektrik
Anvan ou fè nenpòt koneksyon, dekonekte tèminal negatif batri machin nan.
- Fil pouvwa: 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.
- Enstalasyon Fuse: Mete yon 20A fusible into the fuse holder. The 60A fuse included in the RWK82 kit is too large for the KEY2004 and must be replaced.
- Fil tè: 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.
- 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.
- Siyal Antre:
- 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: Si inite prensipal ou a pa gen sòti RCA, konekte fil oratè yo ki soti nan inite prensipal ou a dirèkteman nan amplifier's high-level input harness.
- Oratè Fil: 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:
- Konekte Mikwofòn nan: Plug the Auto-EQ microphone into the dedicated port on the amplifier.
- Plasman Mikwofòn: 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.
- Tann fini: 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).
- Ajiste pwogrè: 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.
- Anviwònman kwazman: Select the desired high-pass filter frequency (60Hz, 80Hz, or 120Hz) using the switches on the amplifier, depending on your speaker size and type.
- Karakteristik opsyonèl: 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.
