This Listing Includes (1) B2 Audio EL CHOLO Monoblock Amplifier (1) Remote Level Control with Monitoring Display The Foundation of the Boulevard For the first time in its history, B2 Audio has engineered an amplifier series dedicated entirely to American custom car culture. EL CHOLO is not a response to a trend. It is a tribute to a lifestyle. From low-and-slow West Coast cruisers to high-output Southeast flex builds, this amplifier was designed from the ground up to reflect the pride, discipline, and craftsmanship of builders who treat their systems as art. This model represents EL CHOLO: The Original — the first release and foundation of an all-new series. Culture Meets Engineering The American sound demands more than big numbers. It demands presence and authority. EL CHOLO delivers the punch and transient response traditionally associated with classic half-bridge designs, re-engineered using modern high-efficiency Class D full-bridge topology. A massive dynamic capacitor bank provides explosive energy reserves without sacrificing thermal control or efficiency. Its long, low-profile chassis mirrors the proportions of a classic lowrider, making EL CHOLO a centerpiece designed to be seen, not hidden. This is power that rolls deep — not loud for the sake of loud. Technical Highlights: Precision Control: Unlike most full-bridge amplifiers that rely on shallow 6 dB or 12 dB filtering, EL CHOLO uses true 24 dB/octave crossovers, eliminating midrange and vocal bleed for clean, authoritative sub-bass output. Massive Energy Reserves: An oversized dynamic capacitor bank delivers explosive impact on demand while maintaining rock-solid stability under extreme electrical load. Show-Ready Architecture: A long heat-sink design, triple 0-gauge power inputs, and full-range capability make EL CHOLO ideal for elite custom installs and competition-grade show vehicles. Thermal Intelligence: A dynamic multi-fan cooling system combined with real-time voltage, temperature, and clip monitoring via the included remote ensures consistent performance during extended play and long boulevard sessions. Built for Builders, Not Beginners EL CHOLO is an elite-tier amplifier designed for experienced installers and advanced systems only. Its power demands require a properly upgraded electrical foundation — high-output alternators, lithium or AGM battery banks, and correct wiring practices. This is not an amplifier for factory electrical systems or shortcuts. It’s built for those who build with intention. Features Up to 13,500 Watts RMS output High-efficiency Class D full-bridge monoblock design Full-range 1-channel capability 24 dB/octave HPF / LPF for precise bass control Dynamic oversized capacitor bank Triple 0-gauge power inputs for extreme current flow Multi-fan dynamic cooling system Remote level control with clip, voltage, and temperature monitoring Long, low chassis for show and custom installations Specifications: Model: EL CHOLO Amplifier Type: Monoblock Circuit Configuration: High-Efficiency Class D Frequency Response: 10 Hz - 20 kHz Signal-to-Noise Ratio: >90 dB Input Sensitivity: 6V - 0.2V Operational Voltage: 9V - 17V Crossover Slope: 24 dB/octave Low Pass Filter: 50 Hz - 20 kHz High Pass Filter: 10 Hz - 2 kHz Subsonic Filter: Adjusted via High Pass Bass EQ: 30 Hz - 80 Hz, 0 -12 dB Power Terminals: 3 x 0 Gauge (67 mm) Fuse Rating: 1000 Amps POWER OUTPUT (RMS @ 14.4V <1% THD) 4 Ohm: 3500W - 4000W 2 Ohm: 7000W - 8000W 1 Ohm: 12,000W - 13,500W Actual power output depends on the electrical system's capability and the quality of the installation. INSTALLATION NOTES Professional installation recommended Requires upgraded vehicle electrical system Use appropriate gauge wiring and fusing Not intended for factory electrical systems Dimensions: Length: 25.19" Width: 9.65" Height: 2.48" Professional Installation Required: EL CHOLO is an elite-tier instrument intended for experienced installers. Because it draws up to 1000 Amps, this amplifier requires a dedicated high-output electrical system (upgraded alternators and lithium/AGM banks).
