Product Research

Features

Marine/MotorSports Amplifier: The JVC KS-DR2104DBT is a Class-D 4-channel amplifier, effectively two full range 2-channel amps built into one chassis. Each pair of channels, labeled channels 1-2 (front) and 3-4 (rear), is independently bridgeable, so the amp can be wired as 4-channel, 3-channel, or 2-channel. Designed for marine and motor sport environments, the amp carries IPX7/6, IP6X, and ASTM B117 ratings.

Note: This amp is designed for Bluetooth audio playback only and does not include any speaker level or preamp level audio inputs.

CTA-2006 Compliant: CTA-2006 is a system of testing and measurement for mobile audio amplifiers. This voluntary standard uses a uniform method for measuring an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring amplifier power uses a DC input voltage of 14.4 volts and the RMS power output is measured over a frequency range of 20 Hz to 20 kHz (for full range amplifiers), with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CTA-2006 standards allow consumers to compare amplifiers and receivers under the same conditions (apples to apples).

CTA-2006 Specifications:

  • Power Output: 50 watts RMS x 4 (@4Ω, 14.4V, 20Hz-20 kHz, ≤ 1.0% THD+N)
  • Signal to Noise Ratio: 74dBA

Other Specifications:

  • Power Output:
    • Into 2Ω: 75 watts RMS x 4 (14.4V, 1 kHz, ≤1.0% THD)
    • Bridged: 150 watts RMS x 2 (14.4V, 1 kHz, ≤1.0% THD)
  • Signal to Noise Ratio: 89 dB (at rated power output)
  • Frequency Response: 10 Hz - 20 kHz (+0/-3 dB)

Amplifier Topology: The Class-D amplifier design offers these benefits:

  • Increased Power Flow: Heavy-duty internal power and ground terminals help increase current flow from the battery connection to the internal circuitry, enhancing sound quality and bass reproduction.
  • High-Quality Capacitors: Polymer Multi-Layer Capacitors were chosen for clear detailed sound with less distortion.
  • Magnetic Shielding: The output coils include magnetic shields to reduce radiated noise and increase sound quality.

Extreme Durability:

  • Waterproof: IPX66/67 certification indicates the amp can withstand high-pressure water spray and brief submersion up to one meter.
  • Dustproof: The IP6X rating is effective against dust entering and damaging the amplifier.
  • Salt Spray Proof: ASTM B117 salt spray and salt fog corrosion testing protects the amp against corrosion/failure in saltwater and other harsh environments.
  • Vibration Proof: The amplifier is made with a die-cast frame that suppresses vibration. The raised middle section on the underside of the amp provides a drain tunnel, helping prevent moisture buildup.

Bluetooth Connectivity: The KS-DR2104DBT is designed for Bluetooth audio streaming from a smartphone, tablet, or other Bluetooth-enabled playback device. The amplifier is compatible with aptX, SBC, and AAC codecs and supports A2DP and AVRCP profiles. Up to five Bluetooth devices can be paired to the amp, letting multiple users stream music; two devices can be connected at the same time, letting you quickly switch playback from one to the other.

Remote Control: The Bluetooth receiver is built into the wired remote, which also provides basic controls for the paired device. Its attached eight foot cable lets you keep the remote within easy reach while the amp is mounted out-of-sight. The remote control can be flush-mounted to the dash or console using the provided bracket (opening approximately 2" tall x 3½" wide, flange 2⅜" x 3⅞"), or can be surface-mounted using the provided double-sided adhesive pad. There is also a ¼-20 threaded insert on the back of the remote (¼" deep) as another mounting option. Along with providing the Bluetooth connection to your device, the remote has the following controls:

  • Play/Pause/Pairing: single button used for pairing a playback device and playing/pausing the music
  • Arrow Buttons: two arrow buttons to skip tracks forward/backwards or fast-forward/fast-backward
  • Bluetooth Indicators: LEDs show Bluetooth connection status
  • EQ/Preout: select one of seven EQ modes - Flat, Hard Rock, Pop, Hip Hop, R&B, Jazz, and Classical; also engages pre-out control mode (pre-out LED lights when activated)
  • Mode Indicator: seven LEDs indicate EQ presets and provide visual of the volume and pre-out level
  • Volume/Control Knob: rotary dial adjusts the amplifier volume, pre-out level, and LED dimmer

Protection Circuits: The amp uses a microprocessor to provide protection against over-heating, shorted speaker wires, low impedance on an output channel, and sending a DC signal to the speaker outputs.

Controls: Behind a weather proof cover on the amp there are additional controls:

  • Fader: rotary control; adjust the front/rear fader
  • Crossover Switch: independent 3-position switches for front and rear channels; LPF (low pass), Off (full range), or HPF (high pass)
  • Crossover Frequency: independent rotary dials for front and rear channels; continuously variable from 50-200 Hz
  • Output Mode: 2-position switch; choose 2-channel when bridging both sides of the amp (to power two speakers); choose 3/4-channel when not bridging (to power four speakers), or only bridging one side of the amp (to power three speakers)

Connections: All of the amp's connections are provided on a single 12" non-removable harness:

  • Power/Ground: 10-gauge wires with an in-line fuse holder on the power wire; a 10-gauge gauge amplifier wiring kit is recommended (sold separately)
  • Fuse: 40-amp ATC fuse in-line on the power input wire
  • Speaker Outputs: four pair of 16-gauge wires
  • Remote Turn-on: 16-gauge wire; used to turn the amp on
  • Preamp Output: one pair of stereo RCA outputs can be used to pass the Bluetooth audio signal out to additional amplifiers or powered speakers
  • Wired Remote Control: 10-pin harness connects the included wired remote control

Q
What speakers should i use with this amp?
[ Michael  Jul 04, 2022 ]
1 answer
A
There are many speakers that can work with this amp. The JVC KS-DR2104DBT outputs 50 watts RMS x 4 at 4 ohms and 75 watts RMS x 4 at 2 ohms and 150 watts RMS x 2 bridged at 4 ohms. Ideally you want the rms and impedance of your speakers to match the rms and impendence of the amplifier. If you need help finding speakers to fit your vehicle or application, call us at 1-800-324-9695 and we'll be happy to help you match some speakers to this amp!

Q
can you run a subwoofer with this amp?
[ marc  May 26, 2022 ]
1 answer
A
Four channel amps can only run four or two speakers in stereo. You would need either a two channel or a mono amp to power a sub.
