- COMPLETE B2 AUDIO BASS PACKAGE: Includes (2) B2 Audio RAGE V3 15-inch dual 2-ohm subwoofers, model B2-RAGE15-D2-V3, (1) B2 Audio RAGE 7800 Class-D monoblock amplifier, model B2-RAGE-7800, and (1) B2 voltage/temperature display bass knob with connection cable.
- 4,000W RMS DUAL-15 SUBWOOFER SYSTEM: Each RAGE V3 15 handles 2,000 watts RMS and 4,000 watts max, providing 4,000 watts RMS and 8,000 watts max combined subwoofer power handling.
- RAGE 7800 2-OHM MONOBLOCK POWER: The included Class-D amplifier delivers 4,200–4,500W RMS at 2 ohms with a sufficient electrical system. Dual 0-gauge power terminals and a 600A fuse rating support the current demands of high-output car audio systems.
- CORRECT 2-OHM WIRING CONFIGURATION: Wire each subwoofer’s dual 2-ohm voice coils in series, then wire both subwoofers in parallel for a 2-ohm final impedance. This is the recommended load for this package; do not wire the subwoofers to 0.5 ohm.
- BUILT FOR HIGH-OUTPUT BASS: RAGE V3 subwoofers feature carbon-fiber cones with integrated dust caps, tall surrounds, massive 600 oz ferrite motors, and 3-inch high-temperature voice coils. Properly sized OFC wiring, fusing, electrical upgrades, enclosure design, and gain setting are required; installation accessories are not included.
B2 Audio Dual RAGE V3 15" 2000W RMS D2 Subwoofers & RAGE 7800W Mono Amplifier Package
This Listing Includes:
- (2) B2 Audio 15" Subwoofer B2-RAGE15-D2-V3
- (1) B2 Audio Mono Amplifier B2-RAGE-7800
- (1) B2 voltage/temperature display bass knob w/ connection cable
Build a powerful B2 Audio bass system with two RAGE V3 15-inch subwoofers and the hard-hitting RAGE 7800 monoblock amplifier. Each B2-RAGE15-D2-V3 handles 2,000 watts RMS, giving this package a combined 4,000-watt RMS subwoofer rating.
The dual 2-ohm RAGE V3 subwoofers are designed to be wired to a 2-ohm final load with the included RAGE 7800. At 2 ohms, the amplifier delivers 4,200 to 4,500 watts RMS with a sufficient electrical system—an excellent power match for this high-output dual-15 build when properly installed and tuned.
RAGE V3 subwoofers feature carbon-fiber cones with integrated dust caps, taller surrounds for enhanced excursion, massive 600 oz ferrite motors, and 3-inch high-temperature voice coils. The RAGE 7800 adds powerful Class-D performance, variable crossover controls, dual 0-gauge power terminals, a voltage/temperature display bass knob, and protection circuitry for serious daily-driver, demo, and SPL-focused systems.
