Product Description
The Rockville RDF-4 delivers powerful, distortion-free audio for your car's sound system with genuine Class D amplification technology. Engineered to power front and rear speakers or bridge channels for subwoofer applications, this compact amplifier fits installations where space is limited. From daily commutes with crystal-clear highs to weekend road trips with deep, resonant lows, the RDF-4 adapts to your listening preferences with configurable crossover settings. High-efficiency design minimizes battery strain while Tiffany-style RCA terminals and LED monitoring indicators simplify installation and performance tracking. Experience clean, powerful sound that brings your music to life with precision and clarity.
Genuine Class D Amplification Technology
The Rockville RDF-4 represents authentic Class D engineering, delivering 175 watts RMS per channel at 2Ω with less than 0.03% distortion. Unlike budget amplifiers using inferior half-bridge designs, this four-channel amplifier features high-speed MOSFET power supply and advanced heat dissipation that maintains performance during extended listening sessions. The dyno-certified power ratings confirm real-world output, giving you confidence in the specifications you're reading.
Compact Installation, Maximum Performance
Measuring just 9.63" x 4.92" x 1.81", the RDF-4 fits in tight spaces without compromising trunk storage. The compact aluminum heatsink design dissipates heat efficiently, tested under full power conditions to prevent thermal protection issues common in competitor models. With 85% efficiency, this amplifier draws minimal current from your vehicle's battery while delivering clean, powerful sound to your speakers. Installation is straightforward with included mounting hardware and 4 AWG power terminals.
Intelligent Monitoring and Control
LED indicators provide real-time feedback on power status, operating mode, and clipping detection, helping you dial in the perfect settings. Tiffany-style RCA terminals create secure connections that maintain signal integrity, while configurable crossover settings (50Hz-250Hz low pass and high pass) let you tailor frequency response for speakers or subwoofers. The input sensitivity range of 224 mVrms to 6.00 Vrms accommodates both factory and aftermarket head units.
Audio Performance That Demands Attention
With a frequency response spanning 5Hz to 45 kHz and a signal-to-noise ratio of 73 dBA, the RDF-4 reproduces your music with remarkable clarity across the entire sonic spectrum. The damping factor of 64.88 maintains tight speaker control for accurate bass reproduction, while stereo separation of -56 dB at 5 kHz preserves the imaging and staging of your original recordings. Bridge channels to produce 350 watts RMS for subwoofer applications.
Ready to Install, Built to Last
Every RDF-4 includes mounting screws, Allen keys, spare fuses, and an owner's manual with video card access to installation tutorials. The amplifier operates across a 9-16.1 VDC range with internal 20A fuses for protection. Meticulously engineered for reliability and performance, this amplifier delivers more true RMS watts per dollar than competing models, bringing studio-quality sound to your vehicle with confidence.
