DD Audio SS4.500 | 500W RMS Super Small 4-Channel High-Speed Class D Amplifier

Product Overview

TheDD Audio SS4.500 is the ultimate solution for high-performance audio in space-constrained environments. Part of the renowned SS Series, this “Super Small” powerhouse delivers a minimum of 125 Watts per channel at 2 Ohms, all from a footprint of just 30 square inches. Whether you are upgrading a motorcycle, a compact car, or a classic truck, the SS4.500 offers zero-compromise sound quality and massive power.

Engineered with high-speed, high-currentClass D circuitry, this amplifier features an upgraded heavy-duty aluminum chassis with 50% thicker walls for superior thermal management. Its a versatile “mini” amp capable of driving full-range components or bridged subwoofers with precision. With High-Level inputs and selectable crossovers, it integrates perfectly into any modern or factory audio setup.

Key Features:

• Ultra-Compact Footprint: Measuring only 5.75″ x 4.5″, it is designed to fit in fairings, under dashes, or beneath seats without sacrificing power.

• Pro-Grade Power: Delivers a continuous 500 Watts RMS total output with high-current MOSFETs and upgraded output devices.

• Advanced Cooling: The signature DD Audio heatsink features extra-long fins to maximize surface area and keep the internal components cool under heavy loads.

• Flexible Integration: Includes High-Level inputs for easy connection to OEM head units and selectable 12dB/Oct HPF/LPF crossovers for precise tuning.

• Robust Connectivity: Features 4 AWG set-screw power terminals and 12 AWG speaker terminals for secure, high-conductivity connections.

Frequently Asked Questions (FAQ)

Q: Can I connect the DD Audio SS4.500 to my vehicle’s original factory radio?

A: Yes! The SS4.500 features High-Level speaker inputs, allowing you to tap directly into factory speaker lines without needing a separate line output converter (LOC).

Q: What wiring gauge is recommended for installing the SS4.500?

A: The amplifier is designed with 4 AWG set-screw power terminals. We recommend using a high-quality 4 AWG Oxygen-Free Copper (OFC) power and ground wire kit for steady current delivery.

Q: Can this amplifier be bridged to drive a subwoofer?

A: Yes! You can bridge Channels 3 and 4 to output 250 Watts RMS at $4\Omega$ to power a single subwoofer, while using Channels 1 and 2 ($2 imes 75ext{W RMS}$) to power your front speakers.
