Product details

Elevate your build with the SS5.500, a true five-channel powerhouse that lets you run crisp mids/highs and seismic bass from a single, compact chassis. DD Audio paired a silky Class AB four-channel front stage with a muscle-efficient Class D mono sub stage, so every note gets an amplifier custom-tuned to its job.

Why it hits different

• Balanced circuit topology – Class AB warmth and imaging for your speakers (80 W × 4 @ 4 Ω; 120 W × 4 @ 2 Ω) plus a dedicated Class D sub channel that delivers 500 W RMS @ 1 Ω without stressing your electrical system.

• Audiophile parts throughout – Elna capacitors, precision resistors and high-spec transistors keep midrange textures lifelike and highs silky-smooth.

• Deep-core bass control – International Rectifier FETs and a dual toroidal power supply unleash rapid current for punchy, accurate low-end, even on stock wiring.

• On-board 12 dB/oct crossovers & sub-sonic filter – Dial in flawless hand-offs (HPF 20-5 kHz, LPF 50-5 kHz, SSF 10-50 Hz) without outboard processors

• Every-install ready – 6 × RCA or high-level inputs accept almost any source; solid set-screw terminals take 4 AWG power and 12 AWG speaker cable

• Remote-gain included – Tweak sub-level from the driver’s seat when the track demands extra slam.

Install it, forget it, feel it

Whether you’re chasing SQ trophies or simply want a clean, integrated solution for your daily driver, the DD Audio SS5.500 delivers studio-grade fidelity and truck-bed-shaking output from a single, elegantly engineered unit.
