Modular Style Meets Functional Cooling — Only from SHCA

Take your amplifier install to the next level with Sky High Car Audio's all-new Passive Cooling Heat Sink Extensions— a never-before-seen upgrade in the world of car audio. These slide-in, color-customizable heat sink add-ons not only enhance thermal performance, but also transform the visual profile of your amp with aggressive styling and premium anodized finishes.

Function + Style: Cool Smarter, Look Better 

Designed to increase surface area, these extruded aluminum extensions improve heat dissipation across the amplifier chassis. Cooler amps mean more consistent performance, longer lifespan, and better output under extreme use — especially in demo and SPL setups.

Each extension is secured to the amp’s factory black heat sink using flush-mount Allen set screws, ensuring a rattle-free, locked-in install even in high-vibration bass builds.

Color Options to Match Any Build

Available in:

• Black
• Gunmetal
• Red
• Blue
• Green
• Gold

  Built for Now — and the Future

  These heat sink extensions are compatible with the full line of SHCA amplifiers, including all current and future mono, 4-channel, and 5-channel models. As we expand the amp lineup, these modular accessories will continue to fit and function flawlessly.
