Sky High Car Audio Passive Cooling Heat Sink Extensions

Modular Style Meets Functional Cooling — Only from Sky High Car Audio

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.

Whether you’re matching theme colors or going all-out with a two-tone design, we’ve got you covered. Want something unique? Contact us directly for in-house custom coloring — we’ll coat these to your exact spec. (Pricing and turnaround time vary.)
