INSTALLATION

Mounting: Choose a structurally sound location to mount your KICKER amplifier. Avoid any damage of the
vehicle’s components like wires, cables, board computer, seat belts, gastank where the screws be driven.
Ensure that this chosen location provide sufficient air circulation for the amplifier. Do not mount the device into
small or sealed spaces without air circulation near by heat dispersing parts or electrical parts of the vehicle. Do
not mount the amplifier on top of a subwooferbox or any other vibrating parts, thereby parts in the inside of the
amplifier may get loosen. Drill four holes using a 3mm bit and use the supplied screws to mount the amplifier.

Wiring: Disconnect the ground connection of vehicle’s battery to avoid an electrical short. Then, connect the
ground wire to the amplifier. Connect the GROUND terminal with a suitable contact ground point on the vehicle’s
chassis. The ground wire must be as short as possible and must be connected to a blank metallic point at the
vehicle’s chassis. Ensure that this ground point has a stable and safe electric connection to the negative “–”pole
of the battery. Check this ground wire from the battery to the ground point if possible and enforce it, if required.
Adding an additional ground wire of a larger gauge between the battery’s negative post and the vehicle chassis is
recommended.

Install a fuse within 30cm of the battery and in-line with the power cable connected to your amplifier. If you ever
need to remove the amplifier from the vehicle after it has been installed, the ground wire should be the last wire
disconnected from the amplifier-just the opposite as when you installed it.

AMP 2

AMP 1

The BX amplifier has two input sections.
The RCA inputs can process the low
level signals from your car stereo’s
source unit. The HI LEVEL INPUT is
suitable to connect loudspeaker wires
of your headunit, if your headunit is not
equipped with preamplifier RCA outputs.
Keep the audio signal cable away from
factory wiring harnesses and other power
wiring if possible. If you need to cross
this wiring, cross it at a 90 degree angle
if possible.

WARNING: Never use the RCA inputs and the HI LEVEL INPUTS at the same time.

Connect the loudspeaker wires of your vehicle according to the drawing above with the included HI LEVEL
INPUT jack. The ground wire (black) must be connected with the ground of vehicle’s chassis.
Then, plug-in the HI LEVEL INPUT jack into the HI LEVEL INPUT socket.

OPERATION

Input Level: The RCA inputs on KICKER BX amplifiers are capable of receiving a Low-level signal from your
source unit. If the only output available from your source unit is a Hi-Level signal, you can use the HI LEVEL
INPUTS. Refer to the wiring section of this manual for additional instructions.

Input Gain Control: The input gain control is not a volume control. It matches the output of the source unit to
the input level of the amplifier. Turn the source unit up to about 3/4 volume (if the source unit goes to 30, turn it
to 25). Next, slowly turn (clockwise) the gain on the amplifier up until you can hear audible distortion, then turn it
down a little.

Bass Boost Control: The variable bass boost control on the top of the amplifier is designed to give you
increased output, 0–12dB, at 40 Hz. The setting for this control is subjective. If you turn it up, you must readjust
the input gain control to avoid clipping the amplifier.

Crossover Control: The variable crossover on the top of the amplifier allows you to adjust the crossover
frequency from 50–200Hz. The setting for this control is subjective; 80Hz is a good place to start.

Crossover Switch: Use the XOVER switch on the end panel of the amplifier to set the internal crossover to
OFF, LP or HP. When the switch is set to OFF, a full bandwidth signal will be amplified. Set the switch to HF if you
want the amplifier’s internal crossover to serve as a high-pass filter. Set the switch to LF if you want the amplifier’s
internal crossover to serve as a low-pass filter. Never change the crossover “OFF-LP-HP” switch setting with the
audio system on!

Input mode: Set to 4CH if you are running two sets of inputs (AMP1 and AMP2) to the
amplifier. Set to 2CH if you want to drive all channels from a single stereo input (AMP1).

Remote Bass-BXRC (not included): When the crossover on your BX amplifier is set to LP pass, you have the
ability to control the output level of the amplifier remotely. To mount the BXRC remote bass level control, simply
screw the housing to the chosen location. Run the cable from the controller to the “Remote Bass” jack on the
amplifier chassis.

Note: When the crossover is set to LP, the BXRC only controls the AMP1 channel.
