One of the hardest problems to overcome in a high power car stereo 

system is providing the tremendous amount of current necessary to feed high
power amplifiers. This is especially critical in subwoofer amplification.
Stillwater Designs engineers have met this challenge with the new DX-Series
amplifiers. Thanks to Class D circuitry, the average current draw is much lower
than with the conventional amplifier designs. Your new KICKER mono block
subwoofer amplifier creates the massive power you need for optimal 
subwoofer performance with much less demand on your vehicle's charging
system than with a conventional amplifier. It also provides a full complement
of features you need for ultimate control of your subwoofer system.

FEATURES & CONTROLS

• Class D switching amplifier for maximum efficiency
• 18dB per octave low pass output filter for better noise rejection
• Maximum power at 2 Ohms on the DX700 and DX350, 1 Ohm on the

DX1400

• Fully regulated power supply for rated output in real-world conditions
• Four-layer printed circuit boards for high current capabilities (DX700

and DX1400)

• Superior output circuit magnetics for better noise rejection 
• 24dB per octave switchable subsonic filter @ 25Hz, 
• Built-in remote gain control circuitry - under-dash remote gain 

controller included

• SWX two-way active electronic crossover module in 

Module Docking Port

• Protection circuitry - short circuit protection, reverse polarity 

protection, over voltage protection, thermal protection

• Silent turn on/off circuitry eliminates speaker damaging “thump”

DX1400, DX700, DX350
