Gravity GTVL74BT 26" Amplified Powersports Soundbar

The Gravity GTVL74BT is an amplified, double-sided powersports marine soundbar designed to add music playback to UTVs, ATVs, golf carts, and other off-road vehicles. It combines eight marine-grade drivers, onboard amplification, Bluetooth streaming, and integrated lighting in one roll-bar-mountable enclosure. This makes it a practical upgrade for riders who want a self-contained audio solution rather than separate speakers and an external amplifier.

Its eight-speaker layout includes two tweeters, four mid-range drivers, and two woofers. The double-sided design is intended to spread sound around the vehicle, while the woofer complement supports fuller low-frequency output than a small full-range-only bar. With a stated maximum output of 800 watts, it is built for open-air powersports use where road, wind, and engine noise can compete with music.

The GTVL74BT supports Bluetooth 5.0 wireless streaming with a stated range of up to 100 feet. An integrated AUX input provides a wired source option when Bluetooth is not preferred. An AUX output is also specified for daisy-chaining compatible wired speakers or subwoofers sold separately.

For outdoor use, the enclosure carries an IP66 waterproof and dustproof rating. The marine-grade speaker system and sealed powersports-oriented format are intended for exposure to rain, mud, sand, and dusty trails. A rear-facing LED light bar adds a visibility-oriented lighting element with adjustable brightness for nighttime use.

Speaker backlighting provides green, red, white, and blue color selections, along with solid, fading, music-sync, and off modes. The included roll-bar mounting bracket fits cage bars from 1.75 to 2.5 inches in diameter. This allows the GTVL74BT to serve as a complete primary audio bar or as the front end of an expanded wired system.

Design & Installation

The GTVL74BT uses a compact, double-sided soundbar format with marine-grade speakers and a weather-resistant enclosure. Its stated IP66 rating addresses water and dust exposure associated with off-road use. The speaker lighting and rear-facing LED light bar are integrated into the enclosure, avoiding the need for separate lighting hardware for these functions.

Use the included roll-bar mounting bracket on compatible 1.75- to 2.5-inch cage bars, then connect the unit to a 12-volt power source. Pair a Bluetooth-enabled phone or media device for wireless playback, or connect a wired source through the AUX input. For a larger system, the AUX output can be used to daisy-chain compatible wired speakers or a subwoofer sold separately.
