Small amp. Big difference.

The Kicker 47KEY2004 isn’t just an amplifier — it’s an automatic DSP tuning system built into a compact chassis. Plug it in, run the included calibration mic, and it tunes your system in minutes.

Factory system upgrade made easy.

🔊 Power Output (RMS)
  • 50W x 4 @ 4Ω

  • 75W x 4 @ 2Ω

Plenty of clean power to wake up factory speakers or run upgraded coaxials/components.

🧠 What Makes KEY Different
  • Automatic DSP Setup (included microphone)

  • Time Alignment

  • 40-band EQ per channel

  • Crossover management

  • Phase correction

  • Auto gain matching

  • Start/Stop vehicle compatible

It literally listens to your system and corrects it.

⚙️ Key Features
  • Compact footprint (easy hidden installs)

  • Accepts speaker-level or RCA inputs

  • FIT+™ integration (OEM safe)

  • Selectable bi-amp mode

  • Built-in crossovers

🚗 Perfect For
  • Factory head unit upgrades

  • Lease-friendly installs

  • OEM integration without replacing radio

  • Daily drivers needing clarity, not just volume

If your stock system sounds muddy or flat, this fixes staging, clarity, and balance without replacing everything.
