Product Research

Features

Overview: The MB Quart Nautic MBQR-SUB-2 Polaris RZR tuned package includes an NA2-400.1 400 x 1 (@2Ω) mono subwoofer amp for powering the included 10" dual voice coil subwoofer.

Compatibility: The MBQR-SUB-2 audio package is designed specifically for installation in 2014-2020 Polaris RZR vehicles, with or without a factory Ride Command audio system.

Installation: The MBQR-SUB-2 10" subwoofer enclosure is designed to mount in place of the factory glove box. If installing the subwoofer and amp combo in a Polaris RZR with an existing MB Quart Stage 2 system (MBQR-STG2-RAD-2 or MBQR-STG2-RC-1), wiring and mounting hardware are provided with those systems to integrate the subwoofer and amp.

  • Note: If you are NOT upgrading an existing RZR Stage 2 system, you will need to determine a mounting location for the amplifier and run additional speaker wire, along with power and ground connections for the amplifier.

Subwoofer: The included 10" subwoofer features a dual 4Ω voice coil design that's wired for 2Ω. The sub comes pre-mounted inside a ported, high-impact HDPE composite enclosure that's designed to mount in place of the factory glove box with no modifications. Powered by the NA2-400.1 400W amplifier, the subwoofer and enclosure combo can provide deep, powerful bass at high volume.

NA2-400.1 Sub Amplifier: The MBQR-SUB-2 sound system includes an NA2-400.1 mono amplifier for driving the subwoofer's dual voice-coils. The Class-D amp outputs 400W @ 2Ω (200W @ 4Ω) and has a frequency response of 20Hz - 20kHz. The amplifier features conformal coated PC boards that resist corrosion from salt spray and moisture, and a Q-Stasis pre-amplifier stage that reduces incoming noise from a headunit, greatly improving sound quality. A dual coil Pulse-Width Modulated power supply keeps a constant steady voltage. The Class-D topology combined with aluminum heat sinks allows the amp to produce the maximum amount of power while keeping it cool. Mounting hardware is included for mounting the amp with the subwoofer enclosure. The amplifier's front and rear panels include the following:

  • Inputs: One pair of RCA jacks provides the audio input for the amp.
  • Outputs: A single 2-wire subwoofer speaker output is provided on a 7" hardwired harness terminated with a 2-pin Molex connector.
  • Power/Ground/Remote: A 7" hardwired harness with Molex connector is provided for power, ground, and remote connections.
  • Wired Remote Input: A 4-pin Molex plug on a 7" harness provides the connection for the included wired remote level control. This can be mounted on the dash or console and includes a 15.5' cable for plugging into the amplifier's harness.
  • LPF: A rotary low-pass filter adjustment ranges from 50Hz - 150Hz.
  • Subsonic: The subsonic filter can remove frequencies below the setting amount, with a range of 15Hz-50Hz.
  • Boost: A 2-way switch (0dB & 12dB) lets you apply a 12dB boost @45Hz.
  • Level: Varies the input signal level with a range of 9V - 0.2V.
