Rockford Fosgate's Power Series Amplifiers
Rockford Fosgate's Power Series Amplifiers
Rockford Fosgate has a well-deserved reputation for building high-quality mobile audio products. Their Power Series amps occupy the top of the amplifier food chain, with fine-tuned audio controls, extreme durability, and proprietary technologies that deliver stronger, more reliable performance than most other amplifiers on the market today.
Rockford Fosgate's high-tech solutions yield more power
Power Series amplifiers actively monitor their speakers' performance using Rockford Fosgate's Constant Power technology. A speaker's impedance naturally fluctuates as it performs. So, just like your cruise control increases the engine's RPM to maintain your car's speed uphill, Constant Power circuitry maintains this amp's output by increasing its internal voltage and current when the speaker's impedance rises. This results in up to a 25% increase in the amp's total power output.
Rockford Fosgate combined analog and switching technologies (Class AD) to produce this highly efficient, full-range amplifier that has very low distortion. It's also stable down to one-ohm per channel, so you can be sure even low-impedance speaker systems will play safely, as well as loudly.
Dynamic Thermal Management
Power Series amps use Rockford Fosgate's patented, award-winning "Dynamic Thermal Management," a 3-stage cooling system that uses forced air to dissipate heat evenly across the amp and out through the large heatsinks. This results in cooler internal components, higher efficiency, and lower distortion.
MEHSA is a Rockford Fosgate proprietary process that increases the heat transfer from the MOSFET devices to the heatsink. This allows the heat to escape more readily from the amplifier, so that the transistors stay cooler.
Extra-quiet inputs
"Differential Input" circuitry helps eliminate any electronically induced noise or hum that could be picked up by the input cables, allowing only clean signals to enter the amplifier. You get more music with less heat and noise in a stylish package that's up to 40% smaller than previous models.
T1000-4ad Power performance
This amp's bigger than its size. Four channels of 250 RMS watts is enough to take most SPL speakers to their extreme limits. Or you can bridge your T1000-4ad to blast 500 watts each to a pair of subwoofers. Either way, you can depend on plenty of clean, powerful sound from your Power Series amp.

Product Research
Features
Class A/D: The T1000-4ad is a Class A/D amplifier, using dynamic switching frequency control to combine the sound quality characteristics of Class-A with the efficiency of Class-D. This technology allows the amplifier to produce more power with less current draw from the vehicle charging system.
Constant Power: The amp is 1Ω stable and the power output doesn't vary with impedance; 250 watts RMS x 4 at 4Ω, 2Ω, and 1Ω, and 500 watts RMS x 2 (bridged) at 4Ω or 2Ω.
Differential Inputs: Differential input circuitry measures the voltage of both the positive and negative sides of the input signal, then subtracts the voltage common to both conductors (noise), resulting in only the original signal. This allows only clean signal to enter the amplifier.
Cast Aluminum Heatsink: The cast aluminum heatsink dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion heatsink designs.
Dynamic Thermal Management (DTM): DTM Evenly distributes excess heat across entire amplifier heatsink.
MEHSA³: MEHSA³ (Maximum Efficiency Heat Sink Application-Third Generation) is a Rockford Fosgate proprietary process that increases the heat transfer from the MOSFET devices to the heatsink. The multi-layer insulated metal MEHSA substrate operates with minimal thermal resistance, spreading heat both downward and outward to quickly dissipate heat from each device across the heatsink. This allows greater power output, enhanced thermal stability, and maximum reliability.
NOMAD: NOMAD (NOn-Multiplying Advanced Decision) is an intelligent protection circuit that uses an analog computer to make real time decisions regarding temperature, voltage, current and impedance. The unit is protected without limiting sound output unless needed.
DSM (Discrete Surface Mount): In the manufacturing process high speed robotics are used to place 1% tolerance parts and large board traces. DSM improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
Power and Protection LEDs: The LEDs are located on top of the amplifier. A blue Power LED illuminates when the amplifier is on. A red Thermal LED will illuminates if the amplifier overheats. The yellow Protect LED illuminates if a short circuit or too low an impedance is detected at the speaker connections.
Controls
Gain Control: The amplifier has independent gain controls for the front and rear amplifier sections, each is continuously variable from 150mV to 5V.
Crossovers: The amplifier's internal front and rear crossovers have independent controls; each can be set to high-pass, all-pass (full range), or low-pass. The crossover point is continuously variable from 50-500 Hz and the slope is 24 dB/octave.
Punch EQ: Punch EQ works along with the crossover switches, and like the crossovers there are independent front and rear Punch EQs dials. When the crossover is set to low-pass, Punch EQ acts as a variable bass boost; 0-18 dB at 45 Hz. When the crossover is set to high-pass, the Punch EQ acts as variable treble boost, 0-12 dB at 12 kHz. When the crossover is set to all-pass, both the bass and treble boost circuits are active.
2/4-Channel Switch: The 2/4-channel switch changes the T1000-4 between 4-channel and 2-channel input mode. When operating in the 2-channel mode, the amplifier produces 4-channels of output with connections to only the front channel inputs.
Connections
Power Connections: The power and ground terminals are nickel plated captive c-clamp wire connectors and will accommodate up to 4-gauge wire. An external 150-amp fuse (not included) must be installed on the power wire. If a wiring kit is used that includes a fuse with a value other than 150-amps, that fuse should be replaced with a 150-amp fuse. The remote turn-on terminal is also a captive c-clamp and will accept wire sizes of 12- to 24-gauge. A Phillips-head or slotted screwdriver (not supplied) is required to tighten/loosen the terminals.
Speaker Connections: The 4-channel nickel plated clamp wire connectors will accept 8-gauge to 18-gauge wire. A Phillips-head or slotted screwdriver (not supplied) is required to tighten/loosen the terminals.
RCA Input Jacks: The front and rear RCA input jacks are nickel-plated to resist signal degradation caused by corrosion.
RCA Output Jacks: The RCA output (Pass-Thru) provides a convenient way to daisy-chain an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the amplifier location.
Remote Punch EQ (PEQ): An RJ-45 jack is provided for connecting an optional wired remote PEQ control (item number 575ROCKPEQ). If you use the remote PEQ, the rear Punch EQ control on the amp is disabled, and replaced by the remote.
Note: Previous model (prior to 2007) Punch Bass and Para-Punch remotes will not work with this amp.
