Power Acoustik CB1‑8000D: High-Impact Monoblock Performance in a Compact Class D Platform

The Power Acoustik CB1‑8000D, part of the Caliber Series, is engineered for enthusiasts who demand serious output without compromising system integrity. Designed around a Class D monoblock topology, this amplifier brings reliable, high-wattage performance to car audio builds that crave both volume and clarity.

Built for bass-heavy systems, the CB1‑8000D delivers 4000W RMS at 1 ohm, with the stability and consistency you'd expect from MOSFET power supply architecture and SMT circuit boards. This amp handles extended playback without heat fatigue, thanks to its thermally optimized internals and efficient design.

Key Performance Features

• 8000W max power output designed for extreme subwoofer systems
• 4000W RMS @ 1Ω, 2700W @ 2Ω, 1800W @ 4Ω—true power flexibility
• Bridgeable monoblock capability for users wanting to push double power through dual-stacked setups
• Low-level RCA inputs (200mV–6V) ensure seamless integration into upgraded or OEM head units
• Variable low-pass, subsonic, and bass boost controls let you precisely tailor your sound curve
• Dash-mounted remote gain control gives on-the-fly volume adjustments without digging under the dash

Durability & Build

Everything about this amplifier speaks to rugged reliability. A die-cast aluminum heatsink keeps thermals under control, while short-circuit, overload, and thermal protection circuits ensure your system stays protected—even when pushed to the limits.

Designed for Installers & Tinkerers Alike

Angled terminals, a single-sided layout, and compact form factor mean easier installs in tight spaces. Whether you're building out a show vehicle or upgrading a daily driver, the CB1‑8000D slots in without the headaches of bulky amp designs.
