Custom-fit sub enclosure

This enclosure replaces the factory glove box and uses the factory glove box door. It fits right into 2014-newer RZRs and also works in 2018 XP Turbo S or 2019 RZR XP models with a simple modification to the enclosure. It's a great upgrade for any MB Quart RZR audio system.

Blends into your RZR's cockpit

Made from rugged, durable fiberglass, the enclosure is finished in a black, textured coating that blends right into your RZR's cockpit. It's paintable, too, so you can customize it to suit your style. A rugged, weatherproof pass-through sub wire is included, along with mounting hardware and step-by-step installation instructions.

Features

Overview: The MBQ-SUBSYS-1 lets you add extra bass to your select Polaris RZR with a 10" subwoofer and custom enclosure, powered with a 400W amplifier, all designed to integrate into the vehicle while taking up as little usable space as possible.

Compatibility:

Vehicle Fit
2014-up RZR Direct fit
2018 XP Turbo S Minor enclosure modifications required
2019 RZR XP

RZR-SUB10 Enclosure: The MBQ-SUBSYS-1 includes a custom-formed ABS enclosure for the included 10" subwoofer. The enclosure gets mounted in place of the factory glove box, while still retaining the original glove box door. It includes a 50" section of speaker wire pre-installed in the enclosure with the internal section of the speaker wire terminated with 2 sets of bare-ends for attaching to both sets of the subwoofer's terminals. The other end of the speaker wire contains a 2-pin Molex plug that plugs directly into the amp's output harness.

FW1-254 Subwoofer: The MB Quart Formula Series 10" subwoofer features a molded polypropylene cone with a Butyl rubber surround, making it resistant to moisture, dirt, and damaging UV rays. Dual 2" high-temperature voice coil formers along with front and rear venting allows more heat dissipation. Each of the subwoofer's two 4Ω voice coils has its own set of spring-loaded push-terminals for easy connection to the enclosure's speaker wire.

NA2-400.1 Amplifier: The STG2-RAD sound system includes an NA2-400.1 two-channel 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.
  • X-Over: A 3-position slide-switch allows selection of either HP, LP, or Off. The HP and LP options include their own crossover dial with the High-pass filter allowing adjustment from 15Hz - 300Hz and the Low-pass filter adjustment ranging from 50Hz - 300Hz.
  • Level: Varies the input signal level with a range of 9V - 0.2V.
