  • (1) Rockville R7EQ 1/2 Din 7 Band Car Audio Equalizer EQ w/ Front, Rear + Sub Output

Description of BG-4000.1D:

Hifonics BRUTUS Gamma Mono subwoofer audio amplifier delivers 4000 watts with Super D Class™ technology that features Ultra-Fi™ MOSFET outputs that are selected for both balance and output power.


  • Low Noise Preamplifier Circuit
    Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion.
  • RCA Inputs
    Nickel-plated RCA jacks create the most efficient High/Low Level audio connection and resist corrosion.
  • Operation Mode
    Mono only
  • Crossover Type
    Variable electronic crossovers allow for complete control of the sound.
  • Electronic Equalizer
    Control of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers.
  • Class / Topology
    Super D-Class™ designs which employ high-speed microprocessors with proprietary D/A conversion algorithms to efficiently control the current consumption. At very high listening levels, Hifonics amplifiers with Super D-Class circuitry result in lower distortion, higher current efficiencies and less heat than conventional D-Class amplifier designs.
  • Output Device Technology
    Pro-Fi™ Output Device Technology: The Ultra-Fi™ MOSFET is designed for music production vs just electronics output power. It produces very musical high power with high efficiency for cooling and minimal distortion.
  • Heat Sink
    Classic aluminum Hifonics design to minimize heat build up on the Ultra-Fi™ output devices.
  • Power Supply
    Simpatico Coil Design: The dual coil Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices.
  • Output Connections
    High temperature impact resistant nickel plated connectors with Allen head set screws which allow for secure termination of wire and creates an erosion resistant seal.
  • Connection Type
    Secure molded connection terminal for all Power, Ground and Speaker connections. Angled for ease of access while creating a clean wire management profile.
  • LED System Protection Circuitry Diagnostics
    Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel.
  • Bass Remote Included
    Wired Bass Remote allows adjustments to bass frequencies from the control which can be mounted anywhere in the vehicle.
  • Phase Adjustment
    Phase 0-180°: Bass drum attack, snap requires phase between deep frequency subwoofers and upper midbass speakers.
  • Strapping
    Power Strapping allows the installer to Sync the input signal and output power to double the rated output of a mono amplifier which will drive a single subwoofer or group of subwoofers. Driving subwoofers with this method doubles the available power to the overall bass system, while insuring each subwoofer receives the exact same power level (output voltage).

Video of RWK01:


The Rockville RWK01 0 AWG (American Wire Gauge) amp kit has the following differences over other amp kits on the market at this price point.

1. Our RCA cables are 100 % copper. These are top of the line RCA cables

2. Better Resistance: The only thing that really matters with wires is the resistance rating. This is a measurement of conductivity and how much signal is lost per foot of wire. Since Rockville wires are made with around 3 times as much copper as any other wire at this price point, these wires have a much better resistance rating which means they will transfer more power to your amps than the other brands.

3. We do not cheat you on the thickness of the wire. These are standard American wire gauge thickness. This is another reason our conductivity is better than anything else at this price point. Other brands in the market place write 4 gauge, but cheat you on the thickness. We are honest about the thickness.

4. The Rockville amplifier installation kits feature a new soft abrasion proof insulating jacket. This rugged PVC outer jacket allows for 100% improved flexibility over standard power cables making them extremely easy to route through your vehicles interior, and it maintains exceptional resistance to grease and oil. The PVC outer jacket can with-stand an extreme temperature range of -40 to 220 degrees F.
