SoundQubed BG1-750 750 Watt Bagger Series Amp (Ultra Compact)

SoundQubed BG1-750 — Monoblock Bagger Amplifier | BG-Series | 750W @ 1Ω

The SoundQubed BG1-750 is the dedicated subwoofer monoblock of the 2024 BG-Series — SoundQubed’s purpose-built line of ultra-compact amplifiers designed for motorcycles, baggers, side-by-sides, boats, golf carts, and any application where space is the primary constraint. Measuring just 9.84" x 3.8" x 1.7", the BG1-750 delivers 750W RMS at 1 ohm, 600W at 2 ohm, and 425W at 4 ohm — serious subwoofer power in a chassis that fits virtually anywhere. When space limits your options, the BG1-750 is the monoblock you need.

The BG1-750 features a fixed LPF crossover (30 Hz–250 Hz) for precise subwoofer frequency control, an infrasonic filter (10 Hz–50 Hz) to protect your driver from extreme low-resonance distortion, and a bass boost of 0–12 dB at 45 Hz for dialing in your low-end punch. It accepts both low-level RCA input (250mV–6V) and automatic high-level input for plug-and-play compatibility with factory head units and OEM audio systems. A remote level control is included so you can adjust your bass from the driver’s seat. With a signal-to-noise ratio of 92 dB, 85% efficiency at 4 ohm, a damping factor of 92, and PCB anti-corrosion protection coating, the BG1-750 is built to perform in the real world — outdoors, on the road, and in the elements.

Powered by a 4GA input with a 40A fuse, the BG1-750 is protected by thermal, overload, short circuit, and voltage input protection circuits. The sleek black case with machined logos and lasered end caps maintains SoundQubed’s premium aesthetic even in the tightest install locations.

Installation Recommendations

Motorcycle / Bagger Subwoofer Install: The BG1-750 is purpose-built for Harley-Davidson baggers and touring bikes that need dedicated subwoofer power. Its 9.84" x 3.8" x 1.7" footprint fits in most saddlebag lids, tour-pak lids, and under-seat locations. Use the automatic high-level input to connect directly to your factory radio. Set the LPF between 80–100 Hz and engage the infrasonic filter to protect your driver below its tuning frequency. Pair with the BG4-700 or BG4-1400 for a complete bagger audio system.

Marine / Side-by-Side / Golf Cart: The anti-corrosion PCB coating makes the BG1-750 an excellent choice for marine and outdoor subwoofer installs. The compact chassis fits in virtually any storage compartment or under-seat location. Use the remote level control for convenient bass adjustment from the driver’s position.

Electrical Requirements: The BG1-750 uses a 4GA power input with a 40A fuse. It is compatible with 12V electrical systems standard on motorcycles, boats, and powersports vehicles.

A: Yes — the BG1-750 features an automatic high-level input that connects directly to your factory radio’s speaker outputs without an aftermarket head unit.

Q: How does the BG1-750 pair with the BG4-700 or BG4-1400?
A: The BG1-750 is the perfect companion monoblock for either BG-Series 4-channel amp. Run the BG4-700 or BG4-1400 for your fairing and rear speakers, and the BG1-750 for dedicated subwoofer duty — a complete, ultra-compact bagger audio system from a single brand.

Q: Is the BG1-750 weatherproof?
A: The BG1-750 features an anti-corrosion PCB coating for durability in outdoor, marine, and motorcycle environments. It is not fully waterproof — protect it from direct water exposure and install in a location with reasonable weather protection.
