Stinger SGJ76 12V 5-3/4 Inch Crossflow Barrel Cooling Fan 43CFM for Custom Amplifier and Component Installations The SGJ76 from Stinger is a 12V crossflow barrel cooling fan measuring 5-3/4 inches in length with a 43CFM airflow rate and a 35dBA sound level. Designed for custom car audio amplifier installations and enclosed component applications where active cooling is required to maintain operating temperatures and protect equipment from heat-related performance loss or damage. Product overview Car audio amplifiers and other high-powered components generate significant heat during operation, particularly when mounted in enclosed spaces such as custom enclosures, under-seat locations, or boot installations with limited natural airflow. The SGJ76 crossflow barrel fan provides active cooling in these environments, moving 43CFM of air across components to dissipate heat and maintain safe operating temperatures. The crossflow barrel design allows the fan to be installed in tight spaces where a standard axial fan would not fit, drawing air in from one end of the barrel and exhausting it from the other in a straight-through flow path. The 35dBA sound level keeps fan noise to a minimum during operation. Easy installation makes the SGJ76 suited to custom amplifier racks, enclosed enclosures, and any application where active cooling is needed in a compact form factor. Features and benefits 43CFM airflow rate: The 43CFM flow rate provides sufficient air movement to dissipate heat from car audio amplifiers and other components operating in enclosed or restricted airflow environments. 35dBA sound level: The low 35dBA operating noise level ensures the fan does not introduce audible noise into the listening environment during operation. Crossflow barrel design: The crossflow barrel form factor allows installation in tight spaces where standard axial fans would not fit, drawing air in from one end and exhausting from the other in a straight-through flow path. 5-3/4 inch length: The compact 5-3/4 inch length suits a range of custom amplifier rack and enclosure installation spaces. 12V operation: Operates on the standard 12V vehicle electrical system, allowing straightforward connection to an accessory switched power source in the installation. Easy installation: Designed for straightforward installation in custom amplifier racks, enclosures, and other component mounting applications requiring active cooling. Technical specs Specification Detail SKU SGJ76 Brand Stinger Fan Type Crossflow barrel Voltage 12V Length 5-3/4 inches Airflow Rate 43CFM Sound Level 35dBA Frequently asked questions What is a crossflow barrel fan?A crossflow barrel fan draws air in from one end of a cylindrical barrel housing and exhausts it from the other end in a straight-through flow path, unlike an axial fan which moves air perpendicular to the fan blade plane. The barrel form factor allows installation in tight, confined spaces where an axial fan would not fit, making it suited to custom amplifier racks and enclosed enclosures. Why does a car audio amplifier need active cooling?Car audio amplifiers generate heat during operation, particularly at higher output levels. In enclosed or restricted airflow mounting locations such as custom enclosures, under-seat installations, and boot builds, this heat can accumulate and cause the amplifier to enter thermal protection mode or reduce output. Active cooling from a fan like the SGJ76 dissipates this heat and maintains safe operating temperatures for sustained performance. How is the SGJ76 connected in the vehicle?The SGJ76 operates on 12V and is typically connected to an accessory switched power source so it runs when the audio system is on. Contact us for guidance on correct wiring and installation for your specific application. Is the SGJ76 suitable for use with subwoofer enclosures?The SGJ76 is primarily designed for cooling amplifiers and electronic components rather than subwoofer enclosures, where airflow management requirements are different.
