Setting it up for optimum performance

Rockford Fosgate's C.L.E.A.N. technology (Calibrated Level Eliminates Audible Noise) setup system ensures your bass will sound as clean and powerful as possible. It's a simple system to use — turn it up until the light shows red, then turn it down until the red light goes out. Speaker-level inputs let you hook this amp up to almost any system, even a factory stereo.

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring amplifier power uses a DC input voltage of 14.4 volts and the RMS power output is measured over a frequency range of 20 Hz to 20 kHz (for full range amplifiers), with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 standards allow consumers to compare car amplifiers and receivers under the same conditions (apples to apples).

CEA-2006 Specifications:

  • Power Output: 400 watts RMS x 1 into 4Ω
  • Signal to Noise Ratio: >75 dBA (measured at 1 watt into 4Ω)

Other Specifications:

  • Power Output:
    • 2Ω: 800 watts RMS x 1 (14.4 volts)
    • 1Ω: 1200 watts RMS x 1 (14.4 volts)

Mounting: The amplifier can be mounted vertically, horizontally, or inverted using the supplied mounting screws; horizontal mounting (right side up) will provide the best cooling.

Controls

Gain: The rotary gain control is labeled 0 to 11, equivalent to 150mV-4V line level or 450mV-12V speaker level.

Infra-Sonic: The variable infrasonic filter (15-40 Hz, 12 dB/octave slope) is designed to prevent frequencies below the capability of the subwoofer from being amplified. This helps reduce distortion, and is particularly useful when powering subs in ported enclosures.

Frequency: The 12dB/octave low-pass crossover is always engaged (it cannot be bypassed). The crossover frequency is set with a rotary dial, continuously variable from 50-250 Hz.

Punch EQ: The Punch EQ bass boost circuit is adjustable from 0 (min) to +18 dB (max) and centered at 45 Hz.

Auto Turn-on Switch: When using speaker level inputs, this switch can be set to On and the amp will turn on when it senses an input signal (DC offset on the left input). When using the RCA inputs a remote turn-on wire must be connected.

Remote Level Control: A wired Remote Level Control is included, allowing you to remotely control the output level of the amplifier from the dash or center console. The remote has a rotary dial, and comes with mounting hardware and a 16' cable.

Remote Dimensions:

  • Width: 1.16" (2" including the mounting flanges)
  • Height: 0.92"
  • Depth: 1.55" (2.375" including knob and wiring)

Connections

Power Terminals: The power and ground set-screw terminals will accommodate up to 4-gauge wire. The set screws are tightened/loosened with the included 3mm hex key.

Fuse: The amplifier does not have an on-board fuse. A 200-amp fuse should be placed on the power wire within 18" of the battery.

Remote Turn-On Terminal: The remote turn-on set-screw terminal will accommodate up to 8-gauge wire. The set screw is tightened/loosened with the included 3mm hex key.

Speaker Terminals: The set-screw speaker terminals will accommodate up to 8-gauge wire. The set screws are tightened/loosened with the included 3mm hex key.

RCA Input: There is one pair of RCA input jacks. The balanced differential inputs are nickel-plated to resist signal degradation caused by corrosion.

RCA Pass-Thru: A pair of nickel-plated RCA pass-thru jacks provides a convenient way to connect an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the amplifier location. The signal from the inputs is passed directly to the RCA outputs.

Speaker Level Inputs: There is a port for the included speaker input harness. If speaker level inputs are used, nothing should be connected to the RCA jacks.

Q
would this amp power 4 Memphis Audio MB824 300 watts RMS at 1 ohm?
[ Jerry  Feb 23, 2021 ]
3 answers
A
Yeah at 1ohm the output is 1200 watts of rms so it could easily power a 300 watt sub
[ AUSTIN  Feb 23, 2021 ]
A
I would say yes it would. As long as you keep the 1 ohm configuration on all 4 subs.
[ JEFFREY  Feb 23, 2021 ]
A
I have mine powering a wet sound 12" single woofer and it is awesome
[ JARRETT  Feb 23, 2021 ]
Q
Would this power my jl 13 w7?
[ Jonathan  Jan 24, 2021 ]
1 answer
A
This amp is not a good match for the JL Audio 13W7 subwoofer. We have advisors that can be reached by calling 1-800-324-9695 who can give a personal recommendation on an amp that is recommended for that subwoofer
[ Paul  Feb 09, 2021 ]  Staff
Q
Will this support a 1400 watt max 12 inch sub?
[ Andrew  Dec 28, 2020 ]
3 answers
A
Yes it should be just fine and more if you run it at 2ohms instead of 1 ohm. Anymore then that and you'll probably blow your subs because Rockford do a little over 1400 true rms and running it at 1ohm will just destroys your single sub
[ WILLIAM CADE  Dec 29, 2020 ]
A
Yes, I matched mine with a 1500W RMS 12 inch sub. This amp is rated to push 1200W RMS of power.
[ MICHAEL  Dec 29, 2020 ]
A
What is the RMS power rating of the sub?
[ MARTIN  Dec 29, 2020 ]
Q
Would it be okay to run this amp at 1ohm for a 600 watt rms t1?
[ Elijah  Nov 01, 2020 ]
1 answer
A
This amp should not be used with one of those subwoofers. It outputs too much power and will likely damage the subwoofer. We carry amps that are a better match for it and I recommend contacting an advisor by calling 1-800-324-9695 to get a personal recommendation on an amp
[ Paul  Nov 18, 2020 ]  Staff
Q
what speaker terminals to use to bridge this amp?
[ travis  Oct 28, 2020 ]
1 answer
A
We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.
[ Calvin  Nov 12, 2020 ]  Staff
Q
do you need RCA cables for it?
[ connor  Jul 23, 2020 ]
1 answer
A
I used rca cable but it has another plug you can tap off your speaker wires
[ MYLES KAIN  Jul 23, 2020 ]
Q
which wiring kit do you recommend?
[ Harrison  Jul 22, 2020 ]
3 answers
A
I recommend 4 gauge and under. I personally am using 4 gauge ofc.
[ ROBERT  Jul 23, 2020 ]
A
I would recommend 2 gauge
[ Tyler  Jul 22, 2020 ]
A
Rockford fosgate 4 gauge wiring kit. Click on accessories on crutchfield for this amp. Hope this helps
[ Shane  Jul 22, 2020 ]
Q
Would this be the right amp to power 2-12 inch DVC 2 Ohm Rockford Fosgate p2 subs for a final impedance of 2 ohms?
[ Carlos  Feb 27, 2020 ]
1 answer
A
Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.
