Our take on the Rockford Fosgate Power T1000-4AD

by Buck Pomerantz
Rockford Fosgate

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

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.

High-grade internal components mean high-power output.

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.

Even heat dispersal for longer life

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.

Maximum Efficiency Heat Sink Application increases heat transfer away from the transistors 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 Inputs prevent noise from entering "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.

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.

Rockford Fosgate Power T1000-4AD

Written By Sasa, Phoenix, ARIZONA on Thursday, July 10, 2014
 
I purchased two T1000-4 ad one to run my 4 tower speakers at 4 ohm and the other one to run my 8 components inside the boat at 2 ohm and I purchased T1500-1bd for my two L7 subs. Amps are really good they put out a lot of clean power at high volume volume. Just make sure you have your amp gains set right. I would recomand either of these amps to anyone. I am JL audio FAN and I always used JL Amps. Only reason I did not use them this time was because my tower speakers needed 200w RMS. Hands down this is an awesome amp and if I do another boat down the road Ill use these amps again. I play music with these amps sometimes 8 HRS straight at 90% volume no problems what's so ever. Keep in MIND I do live in PHOENIX where out side temps reach 110+ and amps are stored where air and water cant get to unless I have fan running. I plan to install small fans to keep them cool. but these last 4 weekends I been using them without fans * hrs straight and AMPs did not clip or over heat. SOOOOOOOOOOOOOOOOoo YES THEY ARE BAD Boys GET THEM u will be happy with them.
Pros:
REALLY GOOD AMP, CLEAN POWER, They put out more than 250RMS my Sheet Said 290wRMS at 4 ohm
Cons:
I wish amp was little bit smaller because its 15 inches long, Gain Adj are on the side I wish they were facing up it would be easier to adj -- and last thing is HEAT these amps do run HOT so don't freak out. if you touch it and its hot. They run Hotter than new JL Audio AMPS But they do put out TWICE the amount POWER :)
