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 Notes
Nodal Voltage Amplifier): This circuit simplifies the
signal path of the amplifier, allowing the signal to travel through the amplifier at a low voltage. The result
is greater reliability, cleaner performance and
exceptional musicality with the speed, durability and power of MOSFETs.
MEHSA (Maximum Efficiency Heatsink
Application): MEHSA is a process that yields up to 5 times better
heat transfer than traditional FET mounting techniques using the exact same
components. A multiplayer insulated metal substrate operating with minimal
thermal resistance spreads heat both downward and outward to quickly dissipate
heat from each device across the heat sink.
Crossover: The built-in low-pass crossover is adjustable from 50 to 250 Hz.
The crossover has a slope of 12 dB/octave.
Bass EQ: The Bass EQ allows you
to adjust the Q from 2 to 4. Q changes the effective bandwidth of the boost
control at the selected frequency. Higher Q values reduce the effective
bandwidth, lower Q values, increase the effective bandwidth with an adjustable
frequency control variable from 25Hz to 100Hz.
Controller: The external controller lets you adjust the gain level (0 to -20
dB) and the bass boost level of the amplifier from anywhere in the vehicle. The
external controller has the following dimensions: W=1.979", H=1.131", D=2.995"
(including the knobs and attached cable).
Subsonic Filter: The subsonic
filter allows the amplifier to block ultra-low frequencies that your subs can't
reproduce, improving the efficiency of your speaker system. The filter is
adjustable from 15 to 50 Hz and has a slope of 12 dB per octave.
Phase Switch: The phase is a
variable control used to adjust the phase of the output signal relative to the
phase of the input signal. The phase is adjustable from 0 to 180°.
Line Outputs: The amp includes
a pair of RCA line outputs for sending an unfiltered signal to another amplifier
or component without splitting the signal.
Front End Defeat: The Front End
Defeat is used to reroute the input signal around the signal processing
circuitry within the amplifier. While in the On position, all gain and crossover
functions are bypassed. This feature was designed for use with external
processors to provide the purest possible signal path through the amplifier.
Inputs and Outputs Notes
Set-screw Terminals: The power,
ground, and remote turn-on terminals are on the power plug connector, which
plugs into the power plug receptacle on the amp. The speaker terminals are on
the speaker plug connectors, which plug into the speaker plug receptacles. The
power and ground set-screw terminals will accept up to 2-gauge wire. The remote
turn-on and speaker set-screw terminals will accept up to 12-gauge wire.
Note: The power and
ground terminals each have an installed sleeve that allows you to use
8-gauge and smaller wire. The sleeves must be removed to use wire larger
Remote: This RJ45 jack allows
you to connect the supplied external controller.
The amplifier uses three 40A fuses, so
its total fuse rating is 120A. Since pre-packaged 4-gauge amplifier wiring kits
normally have 60A or 80A fuses, you will need to replace the fuse and fuse
holder in the kit with a 150A ANL fuse and ANL fuse holder.
