American Bass Godfather 200.4D 4-Channel Amplifier

The American Bass Godfather 200.4D is a compact four-channel digital amplifier that delivers 180W per channel at 2Ω, with flexible crossovers and band-pass capabilities designed for high‑performance four‑speaker installs.

• 4-Channel Full Range Digital configuration: Four independent channels with digital processing for precise, multi‑speaker setups across front and rear channels.
• 2 Ohm RMS Power: 180W per channel at 2Ω, providing strong output into low-impedance speakers without excessive thermal load.
• 4 Ohm RMS Power: 110W per channel at 4Ω, offering efficient performance with higher impedance speakers.
• 4 Ohm Mono Power: 360W x 2 when bridged, enabling a mono output on two channels for a bridged pair (useful for a sub or high‑power mono applications).
• Frequency Response: 10 Hz – 40 kHz, extending well beyond typical listening range for richer bass extension and bright highs.
• Signal-to-Noise Ratio: 85 dB, indicating a relatively low noise floor for cleaner playback.
• Efficiency @ 4Ω: Over 70%, helping reduce heat and battery draw in typical car installations.
• Damping Factor: ~150, contributing to tighter control of speaker motion for more accurate bass.
• Input Sensitivity: 6V to 0.2V, aligning with a wide range of head‑unit outputs for clean, consistent level matching.
• Low Pass Filter: 50 Hz – 8000 Hz to tailor the upper‑frequency content sent to the woofer or full‑range speakers.
• High Pass Filter: 20 Hz – 800 Hz to protect delicate speakers and reduce ultra‑low bass where not desired.
• Multiply (X1, X10): 500 Hz – 8 kHz, offering selectable boost in a specified upper band for musical emphasis.
• Multiply (X1, X10): 200 Hz – 8 kHz, providing another boost path in a lower mid/high region for tonal shaping.
• Band‑Pass Capabilities: Enables focused energy within a defined frequency band for targeted sound staging and efficiency.
• Wired Remote Control and Clipping Indicator: On‑vehicle tuning tools to dial in the perfect balance and monitor peaks in real time.
• Protection & Construction: Multi‑way protection against DC, speaker short, thermal, and voltage threats; double‑sided PCB and surface‑mount technology for reliable performance.
• Fuse Rating: 60A, providing a clear protection standard for the fused power path.
• Dimensions: 7.88" L × 7.15" W × 2.33" H, offering a compact footprint suitable for tight installs.

In a real car audio build, the Godfather 200.4D suits multi‑speaker front/rear systems with the option to bridge channels for a mono high‑power output. The combination of 2Ω stability, wide crossover adjustment, and protective, space‑savvy construction helps you achieve clean, loud, and controlled sound without sacrificing reliability or fitment.
