The FLX700.4PRO takes everything riders love about the FLX series and pushes it further with a built‑in DSP, upgraded connectivity, and advanced tuning capability — all inside one of the smallest high‑performance amplifier chassis available. Engineered specifically for Harley‑Davidson® motorcycles and compact pro‑audio builds, the 700.4PRO delivers clean, dynamic output with full DSP authority and OEM‑friendly integration.

A micro‑chassis footprint designed to fit inside fairings, saddlebags, and tight installation spaces without sacrificing output. Built to deliver maximum power density in the smallest size.

A powerful 6‑channel DSP—4 amplified and 2 pass‑through—giving riders full control over system tuning.
