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.

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.

MEHSA cooling process

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.


T600-4 Power performance

The T600-4 amplifier puts out 100 watts RMS into each of its four channels — more than enough to drive your front and rear speakers to their musical peaks. Or you can bridge your T600-4 to blast 300 watts each to a pair of subwoofers. Either way, you can depend on clean, powerful sound from your Power Series amp.

Features

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 (Maximum Efficiency Heat Sink Application-Third Generation): MEHSA 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.

Trans-ANA (TRANSconductance Active Nodal Amplifier): Trans-ANA is a circuit that allows the audio signal to pass through the amplifier at low voltage. The signal is directly level-shifted to the fixed high voltage rails via a pair of drive transistors. Signal linearity is assured by an active node formed  by the drive transistors at ultrasonic frequencies. The result is crystal clear sound quality.

NOMAD (NOn-Multiplying Advanced Decision): NOMAD 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.

TO-247 MOSFET: The Power T400-4 utilizes ultra high performance MOSFET output devices, giving the amplifier more power handling capability as well as lower thermal impedance for more reliable operation, even under the harshest load conditions.

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 turned on. A red Thermal LED 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. When any of the protection circuits engage, the amp automatically shuts down until the problem is corrected.

Controls

2/4-Channel Switch: The 2/4-channel switch changes the T600-4 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.

Internal Crossovers: The amplifier's internal front and rear crossovers have a 24 dB/octave slope. Each is independently selectable for high-pass, all-pass (full range), or low-pass operation and is variable from 50Hz to 500Hz.

Punch EQ: Punch EQ works along with the crossover switches. Like the crossovers, the front and rear EQs are independent of one another. When the crossover is set to low-pass, the 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.

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. The remote turn-on terminal 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.

Remote Punch EQ (PEQ) Connection: An RJ-45 jack is provided for connecting an optional remote PEQ control (575ROCKPEQ, sold separately). If you use the remote PEQ, the rear Punch EQ control on the amp is disabled, and replaced by the remote. Note: Previous model Punch Bass and Para-Punch remotes will not work with this amp.

Crutchfield asked: Why did you buy this?
A
Amazing best speaker amp i have used and i have used quite alot [ roger  Aug 06, 2017 ]
A
quality [ Joe  Oct 25, 2016 ]
A
I bought a used Jeep TJ a couple years ago with a custom Rockford Fosgate system that is fantastic. Recently one of the channels went out on the current T600-4. Easiest thing to do is to replace with the same amp. The old amp is only 3 years old, so I'm a little concerned about spending this kind of money only to have it go out again. But the sound is perfect! [ Stephen  Jun 14, 2016 ]

Q
Would this be optimal for 2 12 inch subs?
[ Jman1  Oct 30, 2018 ]
5 answers
A
In my opinion it would work but it would not be optimal.
[ Shamarcus  Dec 16, 2018 ]
A
Depending on the subs you're wanting to push with this amp, yes. The amplifier is extremely powerful and generates wattage that will surely surprise you.
[ Harrison  Oct 31, 2018 ]
A
No, this is not an amp that you nerd for that application. This is a full range sub that amplifies the entire sound frequencies. You need a mono-amp that amplifies only yhe lower frequencies for a subwoofer.
[ Thomas  Oct 31, 2018 ]
A
It could work but it would not be optimal. For 2 12s use a 2 channel amp, not a 4 channel
[ Scott  Oct 31, 2018 ]
A
No, the T600 4 channel amp use on your front and rear speakers use T1000 1bd for sub.
[ JOSEPH  Oct 30, 2018 ]
Q
When available how can I get a custom skin for this amp?
[ Marcos  Oct 18, 2017 ]
1 answer
A
We do not offer any custom paint or "skins" for this amplifier.
[ Ryan  Oct 20, 2017 ]  Staff
Q
The head unit that I'm using has only one pair of rear RCA outs. I would like to use this amp as two channel and a sub. Could I use the "pass through" pre outs from the amp and input them into the rear channel inputs of this amp, to make the connection for the sub? Then bridge the wiring to the sub?
[ James  Mar 30, 2017 ]
1 answer
A
The much simpler solution would be to use two RCA Y adapters to split the single pair of outputs from your stereo: http://www.crutchfield.com/p_120RCAY1/item.html Yes. you can use two channels of the amp to power a pair of speakers and bridge the remaining channels to power a 4 Ohm subwoofer. I hope that helps. My Bio: https://www.crutchfield.com/Support/Bio.aspx?bio=5
