• Two input types: Low-level RCA input accepts 250mV–6V, while automatic high-level input connects to factory speaker outputs.
• Remote level control included: Adjust the bass level from the driver’s seat.
• Protection and coating: Thermal, overload, short-circuit, and voltage input protection circuits work alongside anti-corrosion PCB coating.

Technical Specifications

Why Choose This Product?

The BG1-750 is designed for dedicated subwoofer duty where amplifier space is limited. Its compact dimensions suit installations in motorcycles, baggers, side-by-sides, boats, and golf carts, subject to available space and installation requirements.

The black case has machined logos and lasered end caps. Audio Precision instruments are used to verify each amplifier during factory quality control.

Installation & Compatibility Notes

The BG1-750 uses a 4GA power input and a 40A fuse. It is compatible with 12V electrical systems, including those standard on motorcycles, boats, and powersports vehicles. Check the installation location and electrical requirements for your specific vehicle before fitting the amplifier.

For a bagger subwoofer installation, the product guidance recommends setting the low-pass filter between 80–100 Hz and engaging the infrasonic filter below the subwoofer’s tuning frequency. The amplifier’s automatic high-level input is described as a connection option for factory Harley-Davidson and other OEM audio systems.

The anti-corrosion PCB coating is intended for outdoor, marine, and motorcycle environments, but the amplifier is not fully waterproof. Protect it from direct water exposure and install it in a location with reasonable weather protection.
