Sold by AudioSellerz.com

The Sky High Car Audio SHCA3000.4 is a Korean-built 3000W 4-channel full-range amplifier designed for serious front stages, pro-audio door builds, and high-power multi-speaker systems. Part of the SHCA modular amplifier family, this amp combines high output, detailed analog tuning, and flexible wiring options in a chassis that perfectly matches the SHCA3500.1 for clean, symmetrical installs.

Whether you’re running a full active front stage, strong mids and highs, or bridged mid-bass channels, the SHCA3000.4 is built to deliver precision power with real system flexibility.

Key Features

• Korean Engineered & Assembled
  Designed from the ground up using world-class components and Sky High’s modular platform for reliability and performance.

• High Power Full-Range Design
  4-channel Class D full-range amplifier engineered for:

  • Active or semi-active front stages

  • Pro-audio mids and highs

  • Bridged mid-bass or small sub setups

• Minimum Ohm Ratings (Per Configuration)

  • 2 ohm per channel (stereo mode)

  • 4 ohm bridged

  • Not 1 ohm rated – wiring below 2 ohm stereo or 4 ohm bridged is not supported or warrantied

• Voltage & Warranty

  • 17.0 VDC max operating voltage

  • Rated output power at 13.2V @ 2 ohm per channel @ 1000 Hz (all channels loaded)

  • 1-year manufacturer warranty covering defects under proper install conditions

Wiring Configurations

The SHCA3000.4 4-channel car audio amplifier is built to adapt to your system layout:

• 4-Channel Mode – Traditional full-range stereo front and rear

• 3-Channel Mode – Use channels 1 and 2 individually, and bridge channels 3/4 for a stronger mid-bass or small sub stage

• 2-Channel Mode – Bridge channels 1/2 and 3/4 for a pair of high-power outputs

RCA input can be run from 2 or 4 channels of input, making integration easy with different head units and processors.

Dimensions

• 15.75" (L) × 9.92" (W) × 3.13" (H)

The SHCA3000.4 shares the same footprint as the SHCA3500.1, allowing for clean, symmetrical multi-amp racks and walls.

Efficiency & Airflow Built In

The SHCA3000.4 is designed to stay consistent at high volume:

• High-efficiency circuit layout helps reduce internal heat and stress

• Standard acrylic backplate with internally mounted cooling fan assists with airflow and reliability

• Built for long demo sessions, meets, and aggressive daily use without quick thermal drop-off

Customization That Stands Alone

Like the rest of the SHCA amplifier line, the Sky High Car Audio SHCA3000.4 is built to look as good as it plays:

• Flippable Branding System
  Diamond-cut aluminum Sky High logo and model number plates are fully reversible so the logo is always upright regardless of mounting orientation.

• Modular Center Panel (overlays sold separately)
  Drop-in customizable overlays let you tailor the look with:

  • Forged carbon

  • Mirror stainless

  • Paint-matched aluminum

  • Acrylic/plexi light-up options

No adhesive or permanent modification needed—just unbolt, swap, and reinstall.

Power Input Flexibility

For high-output systems, the SHCA platform supports flexible power upgrades:

• Input Expansion Kits (sold separately)
  Add more 12V power delivery points for heavy-use systems. Available in:

  • Cast aluminum

  • CNC’d aircraft-grade aluminum

  • Copper

• Ring Terminal Adapters (sold separately)
  Ideal for tight or show-style panel work, offering secure, clean connections to the amplifier inputs.

Cooling System Expandability

• Passive Cooling Add-Ons (sold separately)
  Slide-in extruded aluminum heat sink overlays increase surface area for additional cooling performance. Available in multiple colors and raw aluminum for custom finishes (powder coat, polish, etc.).

  • Note: Non-anodized coatings can affect cooling potential.

• Active Cooling (sold separately)
  Push/pull fan kits mount to the extruded heat sink extensions and plug into onboard 12V outputs. Optional thermal bridges can link airflow between multiple SHCA amplifiers.

• 2026 Water Cooling Ready
  Designed to support a future bolt-on water-cooled heat sink system (with pump, radiator, and lines) for extreme show and competition builds.

CAT6 Remote System Compatible

• Link up to 12 SHCA amplifiers on a control network

• Control gain, subsonic, low-pass, and phase controls (per supported amp) from a single unit

• Monitor amplifier temperature or system voltage

• Fully compatible with the Sky High Smart Bass Knob for centralized management in complex systems

Mounting Options for High-End Installs

The SHCA3000.4 is built for clean, professional installations:

• Works with Sky High bracket kits (sold separately) for:

  • Stacking

  • Vertical mounting (adjustable or static)

  • Floating wall installs

  • Side-by-side linking

• Slide-lock channels in the heat sink allow bracket placement and adjustment without custom fabrication.

• Optional footless endcaps allow smooth, flush mounting on amp racks or beauty panels.

If you’re building a serious front stage, pro-audio door setup, or multi-speaker system and want a 3000W 4-channel Sky High Car Audio amplifier that matches the look, power, and modular features of the SHCA monoblocks, the SHCA3000.4 is the go-to choice—sold by AudioSellerz.com
