Overview
Stealth Bomber 4-Channel Class-D Full Range Amplifier
Power your entire audio system with the Cerwin-Vega B54 Stealth Bomber 4-Channel Class-D Full Range Amplifier, a compact yet powerful amplifier engineered to deliver exceptional clarity, efficiency, and performance. As part of the advanced Cerwin-Vega Stealth Bomber Series, the B54 amplifier combines high-output capability with a sleek, space-saving design, making it perfect for modern car audio installations where space is limited but performance cannot be compromised.
The Cerwin-Vega B54 4-channel amplifier utilizes high-efficiency Class-D full-range digital amplifier topology, ensuring powerful output with minimal heat and energy loss. This efficient design allows the amplifier to produce clean, dynamic sound while maintaining compact dimensions that fit easily under seats, behind panels, or in tight vehicle compartments.
At its core, the B54 amplifier features a Class-D IR chipset paired with Direct-FET Power MOSFET output technology, delivering stable power and precise signal processing. This advanced architecture allows the amplifier to drive multiple speakers with excellent accuracy, producing crisp highs, detailed midrange, and controlled low-frequency response.
Built for durability, the Stealth Bomber B54 amplifier features an ultra-compact high-density aluminum alloy chassis that provides excellent thermal management and rugged protection. The solid aluminum construction efficiently dissipates heat, allowing the amplifier to perform reliably even during demanding listening sessions.
To protect your system, the amplifier incorporates advanced rollback power and thermal protection, which safeguards the amplifier and connected components during extreme operating conditions. These built-in protection circuits ensure consistent performance and long-term reliability.
The B54 offers flexible audio tuning with switchable 12dB HP/FLAT/LP crossovers, allowing users to configure channels for full-range speakers or bridge channels for subwoofer applications. The VEGA Bass Boost feature enhances low-frequency output, adding powerful impact to your music.
Installation is simplified with the remote turn-on configurator (REM/DC/VOX), enabling seamless integration with both factory and aftermarket head units.

Product Manuals

Stealth Bomber series amplifiers have been the cornerstone of the Cerwin-Vega Mobile brand
Embodying power, precision, and reliability for car audio enthusiasts.
Don't be fooled by the sleek and compact design of Stealth Bomber series amplifiers
They ensure seamless installation while delivering monstrous power output.
I was super skeptical when I seen how small the amp actually is. I installed it in my saddlebags, connected to 28 inch subs and four 5 1/4 inch four range speakers. My bike cranks Super loud. I am very impressed. I am old school so digital amps were not my cup of tea, analog has always been my go to for amplifiers. But in this I needed something tiny. New Gots four gauge. Power input.. it uses all the power.. kudos to CV for the great products.
