Properly sized OFC wiring, fusing, electrical upgrades, enclosure design, and gain setting are required; installation accessories are not included.
B2 Audio Dual RAGE V4 12" 2000W RMS D2 Subwoofers & RAGE 7800W RMS Mono Amplifier Package
This Listing Includes:
- (2) B2 Audio 12" Subwoofer B2-RAGE12-D2-V4
- (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 V4 12-inch subwoofers and the hard-hitting RAGE 7800 monoblock amplifier. Each B2-RAGE12-D2-V4 handles 2,000 watts RMS, giving this package a combined 4,000-watt RMS subwoofer rating.
The dual 2-ohm RAGE V4 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-12 build when properly installed and tuned.
RAGE V4 subwoofers feature an enlarged V4 surround for increased excursion, massive 630 oz magnet assemblies, and 3-inch voice coils built for serious power handling. 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.
