Rockford Fosgate Power Series T1000-4AD 4-Channel Amplifier

The Rockford Fosgate Power Series T1000-4AD is a 4-channel amplifier that blends Class AD fidelity with Class D efficiency for high-current, full-range performance. Built for enthusiasts who demand clean, dynamic power and flexible wiring options, it delivers 1000W RMS total with bridged capability for subwoofer applications.

• Channels: 4-channel design provides front/rear full-range amplification with the option to bridge pairs for higher-subwoofer or two-channel bass applications.
• Total Power: 1000 Watts RMS total (sum of rated power), delivering up to 250W per channel at 4/2/1 Ohm and 500W per pair when bridged—great for multi-amped systems or strong subwoofer performance.
• Bridgeable: Yes, enabling 2-channel bridging for higher-powered pairs (e.g., a pair of subs) from a single amplifier.
• Dynamic Power: PVC/PowerCube ratings show real-world transient output: 270W x 4 @ 4-Ohm, 327W x 4 @ 2-Ohm, 365W x 4 @ 1-Ohm, 619W x 2 @ 4-Ohm Bridged, 654W x 2 @ 2-Ohm Bridged.
• Frequency Response: 20Hz to 20kHz +/-1dB, ensuring wide audio bandwidth with minimal measured deviation across the audible range.
• Input/Split: 150 mV to 5 V input sensitivity; 2CH / 4CH input switch with 1 RCA pair per front and rear input and 1 RCA pass-thru output for easy signal sharing.
• Circuit Topology: Class AD, combining aspects of high-fidelity sound with efficient operation.
• Efficiency: 84.1% @ 4-Ohm, 81.6% @ 2-Ohm, 81% @ 1-Ohm, contributing to cooler operation and better overall system efficiency.
• THD+N: <1.0% at both 4-Ohm and 2-Ohm loads, indicating low distortion under typical listening conditions.
• Crossover/Tone Controls: 24dB/oct Butterworth crossovers with front/rear High-Pass and Low-Pass settings (50Hz-500Hz) and adjustable front/rear Bass (0 to +18dB at 45Hz) and Treble (0 to +12dB at 12kHz).
• Remote/Inputs: Optional Remote PEQ available (overrides rear channel Punch EQ) for precise EQ in a multi-amp setup.
• Indicators: Power (Blue), Thermal (Red), Protect (Yellow) LEDs to quickly diagnose operating state and thermal issues.
• Power/Speaker Wiring: 4 AWG power input and 8–16 AWG speaker wire; designed for solid, automotive-grade connections.
• Cooling: Convection heatsink for passive cooling in typical vehicle environments.
• Operating Voltage: 9–16 VDC, suitable for most automotive electrical systems.
• Recommended Fuse: 150 A (not included) reflects the high-current demands of this amplifier.
• Dimensions: 2.14" H x 8.14" W x 14.91" D (5.42 x 20.68 x 37.86 cm); Shipping weight 14.45 lb (6.55 kg).
• Compliance: CTA-2006 compliant for industry-standard performance expectations.
• Warranty: 2-Year Warranty.

Benefits: In a premium install, the T1000-4AD powers front and rear speakers with distinct channel control while offering bridge options for subwoofers or a second sub pair. The 24dB/oct crossover enables clean separation between highs and lows, and the tone controls let you tailor brightness and depth to match the vehicle acoustic environment. Dynamic Power ratings and Class AD topology provide strong transient response without excessive heat, aided by a convection heatsink and efficient operation. With RCA pass-thru signal sharing and an optional remote EQ, it fits into both simple two-amp builds and more complex multi-amped systems, delivering reliable, high-fidelity power across a wide impedance range.
