Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Inputs and Outputs
(Maximum Efficiency Heat Sink Application): 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
(Tracking Operation Pre-Amplifier Zone):
TOPAZ is a circuit that simply eliminates noise. The TOPAZ circuit allows the
amplifier ground to move with the source unit ground, creating a "noise
elimination" zone just before the preamp section. If there is any noise in
the ground coming down the RCA line to the amplifier, TOPAZ amazingly tracks it
down and eliminates it. The result is a 30-40dB improvement of the isolation
between input ground and chassis ground.
(Discrete Surface Mount): In
the manufacturing process high speed robotics are used to place 0% tolerance
resistors and large board traces providing greater reliability and efficiency.
(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.
INDIGO (INDexed Ideal Gain
Operation): INDIGO is a
circuit that maximizes the output power of the amplifier by making better use of
the power supplied by the car. As the battery voltage drops, INDIGO tightens up
so the amplifier delivers the rated power, resulting in more consistent power
coming from the amp.
The internal crossover is variable from 50-250 Hz, with a 12dB/octave
Butterworth filter. You can choose to use the amplifier in the high pass
cross-over mode (HP), all-pass (AP-full range), or low pass mode (LP).
Remote Punch Bass:
The Punch Bass feature helps correct for acoustical deficiencies in the
listening environment by helping reproduce full range sound without adding
excessive boost. The Punch Bass control has a narrow band adjustment centered at
45Hz, variable from 0dB to +18dB. Using the mounting bracket, the supplied Punch
Bass wired remote can be mounted in any convenient location under your vehicle's
dash. The wired remote is 2.317" wide, 1.515" tall and 1.980"
deep. The included cable is 15' in length.
The amplifier requires one 60-amp fuse (not supplied).
Right Side Of Amplifier:
- Crossover Frequency: variable
cross-over point from 50-250 Hz
- Independent Gain Controls:
these variable gain controls allow you to adjust the output level of each
channel of the amplifier independently.
- Crossover Switch:
allows you to select HP (high-pass), AP (all-pass), or LP (low-pass)
Left Side Of Amplifier:
- B+ (power):
dual platinum-plated set-screw terminals (width: 0.183") can accept up
to 8 gauge wiring each
- GND (ground):
dual platinum-plated set-screw terminal (width: 0.183") can accept up
to 8 gauge wiring each
- REM (remote turn-on):
0.250" quick-slide for remote turn-on lead. Note: A female
quick-slide is supplied.
Right Side of Amplifier:
- Remote Bass Punch Input: RJ-45
connection allows you to remotely adjust the bass boost of this amplifier
from the front of the vehicle (variably select from 0dB to 18dB of bass
boost centered at 45Hz).
- Pre-amp Input:
platinum-plated RCA jacks for left and right channels
- High Level Input: Molex
plug input for included harness
- Speaker Outputs:
platinum-plated set-screw terminals (width: 0.183") for left and right
channels that can accept up to 8 gauge wiring
Input, Power and Ground Wiring:
This amplifier has two power and two ground inputs, and each input can accept 8
gauge wire. If you use an 8-gauge kit with a 60-amp or higher fuse, you only
need to use one power input and one ground input. If the 8-gauge kit does not
have the required fuse, you can upgrade to a 60-amp or higher fuse. For
especially long runs, you may want to use a pre-packaged 4-gauge wiring kit
along with two distribution blocks, 8-gauge power cable and 8-gauge ground cable.
This would involve using both power and ground inputs on the amplifier. Using
this wiring configuration will result in lower voltage drop and better overall
performance. If you do not use a 4-gauge wiring kit with the necessary
additional items for this wiring configuration, you can purchase all the
necessary items separately. The separate parts and wiring needed are as follows:
- Two distribution blocks (each block
should have one 4 gauge input and two 8 gauge outputs)
- One fuse holder capable of
accepting 4 gauge wire
- One 60-amp fuse
- Two power rings for 4 gauge cable
- 4 gauge power cable (to connect the
battery to a fuse holder and the fuse holder to a distribution block with a
4 gauge input)
- 4 gauge ground cable (to connect a
ground point to a distribution block with a 4 gauge input)
- 8 gauge power cable (to connect the
8 gauge outputs of a distribution block to the two 8 gauge power inputs on
- 8 gauge ground cable (to connect
the 8 gauge outputs of a distribution block to the two 8 gauge ground inputs
on the amplifier)
- Remote turn-on cable (speaker wire
can be used as remote turn-on cable)
- One 0.25" female quick slide
(to attach remote turn-on cable to amplifier)
- One patch cable
- Speaker wire
