Sky High Car Audio 5500.1 Amplifier

Sky High Car Audio SHCA5500.1 – All-Purpose Power with Sky High Flexibility

 

The SHCA5500.1 is the sweet spot in the SHCA lineup—built for daily demo monsters, serious sub stages, or front-stage/mid-bass duty where you want more dynamic range, more headroom, and more control without jumping into giant chassis territory. Korean-built, 0.5 ohm stable, and fully modular, it takes everything people love about the 3500.1 and simply turns it up.

 

If you’re upgrading from entry or mid-power amps and want real output with real cooling and install flexibility, the 5500.1 is designed to be that next step.

Power, Ratings & Warranty

 

 

• True 0.5 Ohm Stability
  
• Warrantied and tested to perform under heavy load in real-world conditions
• Operating Voltage
  
• Rated at 13.2VDC @ 1 ohm
• Up to 17.0VDC max operating voltage
• 1-Year Manufacturer Warranty
  
• Covers manufacturer defects from date of purchase, including approved 0.5Ω operation

Dimensions & Footprint

 

 

• Dimensions: 20.47” (L) × 9.92” (W) × 3.13” (H)
• Slightly larger than the SHCA3500.1 but shares the same width, height, and accessory compatibility

 

 

That means easier upgrades and clean symmetry when you’re pairing multiple SHCA amps on a wall or rack.

 

 

 

 

Efficiency & Airflow Built In

 

 

• High-efficiency circuit layout reduces heat and electrical stress
• Standard acrylic backplate with internally mounted cooling fan
• Designed for:
  
• Long play sessions
• Demo events
• High-output daily use
• Built to avoid heat-based drop-off when the volume stays up

 

 

 

 

 

Customization That Stands Alone

 

 

Flippable Branding System

 

• Diamond-cut aluminum Sky High logo and model plates
• Fully reversible so branding stays straight in vertical, horizontal, or stacked layouts

 

 

Modular Center Panel (Sold Separately)

Drop-in overlays, no adhesives or heavy fab:

 

• Forged carbon
• Mirror stainless
• Paint-matched aluminum
• Acrylic/plexi light-up options

 

 

Just unbolt, swap, and bolt back on to match your theme.

 

 

 

 

Power Input Flexibility

 

 

Input Expansion Kits (Sold Separately)

 

• Add more 12V power delivery points for high-demand systems
• Available in:
  
• Cast aluminum
• CNC’d aircraft-grade aluminum
• Copper

 

 

Ring Terminal Adapters (Sold Separately)

 

• Ideal for tight fitments and ultra-clean panel work
• Bolt-on design for secure, high-conductivity connections

 

 

 

 

 

Cooling System Expandability

 

 

Passive Cooling Add-Ons (Sold Separately)

 

• Slide-in extruded aluminum heatsink overlays
• Increase surface area by up to 25%
• Available in 5 color options plus raw aluminum for custom finishing
• Note: Non-anodized coatings can affect cooling potential

 

 

Active Cooling (Sold Separately)

 

• Push/pull fan kits mount to the extruded heatsink extensions
• Plug into the (4) onboard 12V outputs
• Optional thermal bridges link airflow between linked amps

 

 

2026 Water Cooling Ready

CAT6 Remote System

 

 

• Link up to 12 SHCA amps over CAT6
• Control gain, subsonic, LPF, and phase from a single remote unit
• Monitor amplifier temperature and voltage
• Fully compatible with the Sky High Smart Bass Knob

 

 

 

 

 

Mounting Options for High-End Builds

 

 

As with the rest of the SHCA line, the 5500.1 is designed around modular mounting so it can live wherever your layout needs it:

 

Bracket Kits (Sold Separately) Allow:
