Sky High Car Audio SH-3000.4 – Precision Power. Full Flexibility.
The SH-3000.4 is built for high-output front stages, active three-way systems, or bridged mids that demand clean tuning control and serious power. With Korean engineering, modular cooling, customizable cosmetics, and full active capability, this 4-channel amplifier gives installers and competitors unmatched flexibility and control.
🔥 Key Features
- 2 OHM Stable Per Channel – Optimal performance and reliability in 4-channel mode.
- Bridgeable – Run 3-channel or 2-channel modes for powerful midbass or mids setups.
- Not 1 OHM Rated – Wiring below 2 OHM stereo or 4 OHM bridged is not supported or warrantied.
- Korean Built Class D Platform – Ultra fast-switching with balanced input circuitry.
- Individually QC Tested – Every amp is verified before it leaves the factory.
- 17.0vdc Max Operating Voltage – Rated at 13.2vdc @ 2 OHM per channel.
- Full Active Capable – High-resolution analog tuning across all channels.
- Acrylic Backplate + Internal Fan – Maintains airflow and thermal stability.
- Modular Cooling System – Three levels of expandable cooling options.
- 1-Year Manufacturer Warranty
📏 Dimensions
- Length: 15.75 inch
- Width: 9.92 inch
- Height: 3.13 inch
- Matches the SH-3500.1 for clean multi-amp symmetry.
🔧 Wiring Configurations
- 4-Channel Mode: Full-range stereo
- 3-Channel Mode: Channels 1/2 independent + channels 3/4 bridged
- 2-Channel Mode: Bridges channels 1/2 and 3/4
- RCA Input Options: Can be run from 2-channel or 4-channel signal
❄️ Efficiency & Airflow
- Efficient circuit layout reduces internal heat and stress.
- Acrylic backplate includes an internally mounted cooling fan.
- Built for long play sessions, demo events, and high-output active systems.
🎨 Customization That Stands Alone
Flippable Branding System
- Diamond-cut Sky High logo and model plates flip for perfect orientation.
Modular Center Panel (optional overlays sold separately)
- Forged carbon
- Mirror stainless
- Paint-matched aluminum
- Acrylic/plexi LED options
- No adhesives — bolt-on design swaps in seconds.
⚡ Power Input Flexibility
Input Expansion Kits (sold separately)
- Add additional 12V power delivery points for demanding builds.
- Available in cast aluminum, CNC aircraft aluminum, and copper.
Ring Terminal Adapters (sold separately)
- Ideal for tight installs and clean wiring layouts.
- High-conductivity bolt-on terminal design.
❄️ Cooling System Expandability
Passive Cooling Add-Ons (sold separately)
- Slide-in extruded aluminum heat sink overlays increase surface area up to 25%.
- Available raw or in five standard colors; custom coatings and chrome/copper/gold finishes available.
- Note: Non-anodized coatings reduce thermal efficiency.
Active Cooling Kits (sold separately)
- Push/pull fans mount to passive heat sink extensions.
- Plug into four onboard 12V fan outputs.
- Optional thermal bridges link airflow across multiple amps.
2026 Water Cooling Ready
- Future bolt-on water-cooled heat sink system will include pump, radiator, lines, and optional tank.
🔗 CAT6 Remote System Compatible
- Link up to 12 SHCA amplifiers.
- Control gain, subsonic, LPF, and phase from one interface.
- Monitor amplifier voltage and temperature.
- Fully compatible with the Sky High Smart Bass Knob.
🛠️ Mounting Options
- Stacking, vertical mounting, floating installs, and linked configurations with optional brackets.
- Bracket materials: Extruded aluminum, cast aluminum, billet aluminum (show grade).
- Slide-lock channels built directly into the heat sink for secure modular mounting.
- Optional footless endcaps for clean flush-wall installation.
🎚️ Detented Signal Tuning
- Tactical "click-lock" potentiometers for:
- • Low-Pass
- • High-Pass
- Provides tactile, repeatable tuning — no tools, no guessing.
The SH-3000.4 delivers high-resolution control, modular flexibility, and the power to scale your entire front stage. Precision-built and ready for any system.

REVIEW
Plan the power behind your amplifier.
Amplifiers need the right subwoofer or speaker load, power wire, fusing, ground, and electrical support. Confirm the full system before ordering high-output gear.
