Strappable Power
The DPX1800 and DPX11500 amplifiers are both
strappable. This means, a pair of amplifiers can be
used on a single voice coil to provide additional
power production for extreme SPL levels. A pair
of DPX1800 amplifiers would produce 1,600W
into a 2 or 4 Ohm load, and a pair of DPX11500
would produce 3,000W into a 2 or 4 Ohm load.
Remote Bass Control
The Clarion DPX1800 and
DPX11500 amplifiers include the
option to connect a Remote Bass Control mod-
ule. This allows you to install a subwoofer level
control in the front of your vehicle and control the
low frequency system even when connected to a
source unit (factory or aftermarket) that does not
include a subwoofer output level control.
Adjustable Subsonic Filter
Clarion’s new DPX1800 and
DPX11500 amplifiers feature an
adjustable subsonic filter. This filter is adjustable
from 10Hz to 80Hz using a potentiometer on the
end panel of the amplifier.
When using subwoofers in vented cabinets with
high tuning frequencies (above 35Hz), physi-
cal power handling of the driver may easily be
exceeded. The use of a subsonic filter will limit the
amount of ultra-low frequency information being
passed through to the speaker, as well as reduce
the amount of power the amplifier consumes in
amplifying those low frequencies.
Mixed-Mode Operation
Clarion amplifiers use an inverting circuit that
allows a single 2-channel amplifier to drive multi-
ple satellite speakers in stereo and a subwoofer in
a bridged-mono configuration.
When used in conjunction with passive crossover
components, a Clarion amplifier is capable of
mixed mode operation that can power an entire
audio system.

multi-voltage power supply. The result is tight,
controlled, dynamic power output with excellent
amplifier efficiency.
How does Class G work? Think of the new
Dodge Hemi or Cadillac Northstar engines. These
engines have the ability to shut down a number
of cylinders to reduce fuel comsumption and
heat generation under light loads. The power
supply of a Class G amplifiers works in exactly
the same way. When you aren’t cranking on the
amp, the power supply rail voltage turns down.
The effect, less current is passed through the
output devices, dramatically reducing wasted
power.
The graph below compares the efficiency of a con-
ventional Class AB 1500W amp to our DPX11500
1500W amplifier. You can see that around 350W
DPX11500 is ~65% efficient, whereas the con-
ventional Class AB is merely 25% efficient. This
means, that the DPX11500 is drawing only 37A
of current, where the Class AB amp would be
drawing closer to 97A of current.
Automatic Impedance Matching
The Clarion DPX1800 and DPX11500 amplifiers
feature an automatic impedance sensing circuit
that allows the amp to produce full power into 1
or 2 Ohm loads. This allows a retailer to sell this
amp to a customer with almost any combination
of speaker impedances, and know that they will
get full power from the amplifier.
This new impedance matching circuit operates
invisibly to the installer. No switches need to be
set, no adjustments need to be made. Connect
the speakers and go.
