Cicada Audio BFA5000.1 — 1-Channel Extreme-Power Class-D Motorcycle Subwoofer Amplifier (5,000W RMS @ 2Ω)
Cicada Audio BFA5000.1 — Extreme 5,000W Mono Class-D Amplifier for Motorcycle Subwoofers & SPL Bagger Builds
This is the biggest, baddest mono amplifier Cicada has ever built — and it’s motorcycle ready.
The Cicada Audio BFA5000.1 is an ultra-high-output Class-D mono amplifier engineered to deliver up to 5,000W RMS @ 2Ω from a compact, motorcycle-friendly chassis. Designed for SPL-style Harley baggers, extreme subwoofer systems, and riders who want truly earth-moving bass, the BFA5000.1 provides unmatched output, stability, and control.
With oversized power connections, advanced thermal design, and vibration-resistant construction, this amplifier thrives in real motorcycle environments — enclosed saddlebags, high heat, long rides, and heavy electrical demand. If your Harley needs serious low-frequency authority, this is the tool for the job.
