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

WIRING INSTRUCTIONS
WARNING- Shock Hazard: This series of Class D amplifiers has high voltage DC present
on the speaker terminals any time the amplifier is turned on. Avoid contact with the
speaker connectors and wiring while the system is operational.
IMPORTANT SAFETY NOTES: Never make any wiring connections with power applied to the
system. The risk of damage to components is very high. All power and speaker
connectors will accept up to 8 gauge wire with these exceptions: DX700 and the DX1400
power and ground connections are designed for 4 gauge. Although the average current
draw on the Class D amplifier is lower, the peak demand is about the same as for a
conventional amplifier. It is very important that the screws in the amplifier's terminal strips
are very tight. An allen wrench is included for this purpose. Always make the ground
connection first when installing this amplifier and disconnect ground last when removing it
from the system.
Connect the ground wire, which is 24 inches or less, to a structural chassis member.
Be sure the connection is to bare metal and securely screwed or bolted. (It is not
recommended to run the ground wire to the battery). Check the factory ground wire at
the battery. Besides the large wire going to the engine block, there should be a smaller
wire going from the battery negative to the body of the vehicle. If this wire is smaller than
the recommended power wires shown below, then this ground wire needs to be enlarged.
Run a positive wire of the size shown below directly to the positive terminal of the battery
and use a fuse of appropriate size within 18 inches of the battery. This fuse protects the
wire run from the battery.
Please refer to wire gauge selection chart below for minimal loss at full rated power
under test conditions:
Model Up to 10 feet 10-20 feet
DX1400 2ga. 0ga.
DX700 4ga. 2ga.
DX350 8ga. 4ga.
Inline fuse values (used at the battery):
DX1400 = 150A (supplied with amp).
DX700 = 90A
DX350 = 50A
When running the signal (RCA) cables, keep them away from all power wires in the
vehicle to avoid noise. If a signal cable must cross power wires, try to make the junction at
90 degrees. This will have the least chance of picking up noise.
Note: In the case where the recommended wire size is larger than the
amplifier's connector, it may be necessary to use a power distribution block or
inline connector to adapt down to the size your amp will accept.

MOUNTING INSTRUCTIONS
The orientation of the amplifier is critical to proper cooling. The cooling fins are
designed to operate best when the amp is in a vertical position or mounted flat with the
fins up. It is important to keep the chassis of the amplifier isolated from the metal of the
vehicle because the heatsink is connected to signal ground for noise isolation. Grounding
the heatsink will cause a ground loop. The plastic inserts in the mounting feet of the amp
should remain in place as isolators. These inserts are designed to accept #8 screws for
mounting.
