Description
Stinger SGJ78 12V 8-1/4 Inch Crossflow Barrel Cooling Fan 54CFM for Tight Space Component and Amplifier Cooling
The SGJ78 from Stinger is a 12V crossflow barrel cooling fan measuring 8-1/4 inches (209.5mm) in length with a 54CFM airflow rate and a 0.19 amp draw. Designed for car audio amplifier installations and enclosed component applications where active cooling is needed in tight spaces with little to no natural airflow. The simple 2-wire hookup makes installation straightforward in any 12V application.
Product overview
Car audio amplifiers and other 12V components generate heat during operation, particularly in enclosed spaces such as custom enclosures, under-seat locations, and boot builds where natural airflow is limited. The SGJ78 crossflow barrel fan provides active cooling in these environments, moving 54CFM of air across components to dissipate heat and maintain safe operating temperatures.
The crossflow barrel design draws air in from one end and exhausts it from the other in a straight-through flow path, allowing installation in cavities and tight spaces where a standard axial fan would not fit. At 0.19 amp draw the SGJ78 places minimal load on the vehicle electrical system, and the simple 2-wire connection makes it easy to wire to an accessory switched power source. The SGJ78 is the larger counterpart to the SGJ76 (5-3/4 inch, 43CFM), providing greater airflow capacity for larger amplifier installations or enclosures requiring more cooling volume.
Features and benefits
54CFM airflow rate: The 54CFM flow rate provides strong air movement to dissipate heat from car audio amplifiers and other components operating in enclosed or restricted airflow environments, delivering greater cooling capacity than the SGJ76.
Crossflow barrel design for tight spaces: The crossflow barrel form factor allows installation in cavities and tight spaces where standard axial fans would not fit, drawing air in from one end and exhausting it from the other in a straight-through flow path.
8-1/4 inch length (209.5mm): The larger barrel length suits amplifier racks, enclosures, and component mounting applications requiring a longer fan unit and greater airflow volume than the SGJ76.
Low 0.19 amp draw: The minimal 0.19 amp current draw places negligible load on the vehicle electrical system during operation.
Simple 2-wire hookup: The straightforward 2-wire connection allows easy installation to any 12V accessory switched power source without complex wiring.
12V operation: Operates on the standard 12V vehicle electrical system, compatible with all standard automotive installations.

Frequently asked questions
What is the difference between the SGJ78 and the SGJ76?
Both are 12V crossflow barrel fans with identical design and application. The SGJ76 is 5-3/4 inches in length with a 43CFM airflow rate, suited to smaller amplifier racks and enclosures. The SGJ78 is 8-1/4 inches in length with a 54CFM airflow rate, providing greater cooling capacity for larger installations. Select the size that suits the available mounting space and cooling requirement of your specific installation.
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.
How is the SGJ78 connected in the vehicle?
The SGJ78 uses a simple 2-wire hookup and operates on 12V. It 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.
What is the current draw of the SGJ78?
The SGJ78 draws 0.19 amps during operation, placing minimal load on the vehicle electrical system and making it suitable for connection to most accessory switched circuits without concern for current draw.
What mounting hardware is included with the SGJ78?
Mounting hardware details are not confirmed in the available source data for this product. Contact us before ordering to confirm what is included and what additional hardware may be required for your specific installation.
