Gravity GRS36LED 36-Inch RGB Bluetooth Soundbar

The Gravity GRS36LED is a 36-inch amplified soundbar designed to bring full-range music playback to UTVs, ATVs, trucks, cars, boats, and other 12-volt applications. It combines multiple speakers, Bluetooth streaming, wired inputs, and integrated RGB lighting in one enclosure. This makes it a practical option for adding audio where a conventional component-speaker installation may be less convenient.

Its speaker array includes six 4-inch full-range drivers and two 1-inch soft-dome tweeters. That combination is intended to cover bass, midrange, and high-frequency detail across a stated 45 Hz to 22 kHz frequency response. A built-in amplifier powers the system, eliminating the need to source a separate amplifier for basic operation.

The GRS36LED supports Bluetooth 5.0 wireless streaming with a stated range of up to 33 feet. USB playback and line-level input add wired source options for compatible devices. An RCA output is also provided for connection within a larger audio setup.

Integrated RGB LED lighting gives the soundbar a visual accent in addition to its audio role. Multiple color modes, adjustable brightness, and adjustable lighting speed let the appearance be tailored to the vehicle or installation. The included RF remote is specified to work from up to 25 feet and can be used for audio and lighting adjustments.

Designed for 12-volt electrical systems, the GRS36LED operates across a stated 10 to 16 volt range. It can serve as a standalone audio solution or as a source component within a broader vehicle sound system. Its combination of onboard amplification, multi-source connectivity, and supplied mounting hardware supports installations focused on off-road, automotive, and marine-style use.

Design & Installation

The GRS36LED uses a 36-inch soundbar layout with an integrated amplifier, six full-range speakers, dual tweeters, and built-in RGB LED lighting. The available product information identifies it as having durable construction for outdoor and marine-oriented applications, but does not specify enclosure materials or an ingress-protection rating. Its all-in-one design reduces the number of separate audio components needed for an installation.

Mounting brackets, hardware, power and connection cables, an RF remote, and a user manual are included. Install the soundbar on a suitable vehicle mounting surface, connect it to a compatible 10 to 16 volt power system, and select Bluetooth, USB, or line-in as the desired source. The RCA output can be used when integrating compatible downstream audio equipment.
