MB Quart Polaris RZR XP4 1000 in the Arizona Desert

The one and the only MB Quart Polaris RZR was introduced at SEMA. MB Quart revealed a stunning yet easily doable Powersports system with the Polaris RZR to develop a one of a kind, customized experience that will turns heads and drive off-road enthusiast to any retailer! It is a fully loaded powersports, off-road vehicle to guarantee jealousy among enthusiast and professionals alike.

The SEMA Show is not open to the general public. SEMA is a trade-only event and only qualified individuals employed within the automotive aftermarket industry are permitted to attend. Understandably, the MB Quart booth was packed with many dealers who are interested in growing their business in the Powersports, off-road vehicles, and marine categories. Even a few consumers stopped by to check out the new products on the last day. The outdoor area is open to the public on the last day for the SEMA Parade.

The MB Quart Polaris RZR is packed with amazing new gear to keep the music blasting in the harshest of terrains. The RZR is loaded with the following upgrades:


Modified dash holds a GMR-2 and UTV INC switch panels and switches

GMR-2 is a Bluetooth source unit with built in power including AM/FM and MP3. This unit features Apple control which brings more control between your Apple devices and the headunit. The GMR-2 will accommodate up to two GMRWDR wired remote controls. The GMR-2 Bluetooth head unit is waterproof with built in power which makes it easy to install a simple four channel system that does not require an amplifier. However, with the included RCA output an amplifier can easily be added to the system for additional speakers or a subwoofer system.


GMRWDR wired remote mounted between rear seats for passenger control of audio system

GMRWDR is a wired remote specifically designed for the GMR-2. The unit allows riders in the rear of the MB Quart Polaris RZR to have control while the pilot minds the dunes or the trail. In a boat, the pilot house can have the main GMR-2 unit while the cabin and swim deck can each have GMRWDR unit. The unit is waterproof and has the same gauge mount opening as the GMR-2.


PSAP-2 Accessory Plug

PSAP-2 is an essential accessory for the GMR-2 or the GMR-1. Put the USB charging jack and the 3.5 mm input cables in the dash or somewhere they can be at arm’s length rather than only accessing these connections from the back of the units. It is easy to install and has a rubber cap to seal in the connection when not in use.


NT1-120L mounted to Offroad Sound Systems Waketower Bar

NT1-120 is one of the MB Quart award winning, marine certified tower speaker which will delivers 8” of woofer with a 1” pure titanium dome tweeter. The unique mounting system is steel reinforced and includes 11 various mounting options for cages or towers from 1.5″ to 2.75″. All hardware is included with every tower. Perfect for boats, off-road vehicles or project vehicles that need audio installation. The speaker features water resistant components to the IPX67 standard, including woofer cones, titanium tweeters and rust resistant internal connectors. The centering ring allows the speakers to tip left/right when mounted to an arced pipe assuring that the speaker looks level. The NT1-120 is available in illuminated and non-illuminated.


NK1-116L mounted in Offroad Sound Systems door panels

NK1-116 is also an award winning Nautic series marine and powersports speaker by MB Quart just launched a few weeks before SEMA. The speakers feature water resistant components to the IPX67 standard, including mid-range cones, titanium tweeters and rust resistant connectors.  The NK1-116 is available in illuminated and non-illuminated.

The NK1 Series are also is available in an 8″ 2-way, seen below with French Canadian Pro Motocross Racer Cynthia Gauthier. This configuration is very unique for Marine and Powersports. The saying is true, “size matters” and having an 8″ coax solution could be perfect when an additional subwoofer may not fit the bill. This pair of 8″ 2-ways make a huge amount of bass. Of course, the NK1 8″ speakers are also available in illuminated and non-illuminated.
