Mounting Instructions

When selecting a location to mount your Kicker amplifier be sure it is structurally sound and that there are no items behind the area where the screws will be driven that could be damaged. Check for wire harnesses, brake lines, fuel lines, gas tanks, etc.

All amplifiers generate heat under normal operation. Be sure to choose a location that allows adequate ventilation for the amplifier. Also consider that the air temperature inside an automobiles trunk can reach upwards of 140 degrees fahrenheit. An amplifier mounted here may require additional cooling tactics such as fans or venting to allow cool operation. If possible, mounting the amp in the passenger compartment will allow cooler operation.

Remember that the controls on top of the amp will need to be accessible for adjustment later. Keep this in mind as you choose your amplifier’s mounting location.

Now that you are ready to mount your amplifier, use the supplied 3mm allen wrench to remove the amplifier shroud. This will give you access to the mounting holes in the amplifier and all wiring connections.

With the shroud removed, you now have access to the four mounting holes in the mounting feet and all wiring connections. Drill 4 holes using a 7/64” drill bit and use the supplied #8 screws to mount the amplifier.

Wiring Instructions

Signal can be input into the amplifier using either the low level RCA input connections or the high level (speaker level) connections. Using the low level RCA connections is the preferred method. Use the high level inputs only if your head unit does not have low level RCA type outputs.

When using both sets of High Level inputs on the KX700.5, the supplied RCA dummy plugs must be inserted into the AMP 2 inputs in order for the fader to work properly. If the amplifier is being used in any other configuration DO NOT USE THE RCA DUMMY PLUGS! 

The use of twisted pair interconnects is recommended for all installations to minimize noise. When routing these cables through the automobile, try to keep them away from factory wiring harnesses and other power wiring. If you need to cross any of this wiring do so at a 90 degree angle to reduce the potential of noise problems.

When working with power connections it is always recommended that you disconnect the battery to prevent accidents.

The ground should be connected to the amplifier first before making any of the other connections. This wire should be as short as possible (24 inches or less)and connected to a paint/corrosion free solid metal area of the car’s chassis. Use the same gauge wire as recommended for the amplifiers power connection to the battery. Adding an additional ground wire between the car battery’s negative post and the car chassis of this same gauge (or larger) is also recommended. If you ever need to remove the amp 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.

A fuse must be installed within 18 inches of the battery to protect the power wire feeding your amplifier. This fuse should be of at least the same value used in the amplifier but no higher than the capacity of the wire. See the chart below for wire size and fusing recommendations.

Remote Bass Level Control

When using the Remote Bass Level Control you have the ability to control the level of the subs from the driver’s seat. To mount the controller simply screw the metal bracket to the chosen location, then slide the housing onto the bracket until it snaps into place. Run the cable from the controller to the appropriate jack on the amplifier chassis.

System Diagrams

The following diagrams show the most common configurations for your system.

Stereo Operation with Subwoofer
KX amplifiers are capable of operating into a minimum impedance of 2 ohms per channel in stereo operation and 2 Ohm mono on the subwoofer channel.
 

All Channels Bridged

The KX700.5 is capable of bridged operation on AMP 1 and AMP 2. This, for example, would allow you to bridge AMP 1 to run the Right side and AMP 2 torun the Left side. But remember AMP 1 and AMP 2 are only stable down to 4 ohm mono.

Adjusting Amplifier Controls

On your Kicker amplifier there are Five (Seven on the KX700.5) rotary controls on top and one (two on the KX700.5) switch(es) on the end panel. These controls ensure the reliability and performance of the amplifier, so they need to be set correctly

CROSSOVER SWITCH
NEVER CHANGE THE CROSSOVER SWITCH SETTING WITH THE SYSTEM ON!
The switch located on the end panel next to the RCA jacks is for setting the internal crossover. In the OFF position the amplifier passes a full range signal to the speakers. The HI position should be selected when connected to any speakers which you do not want to receive sub-bass information.

BEFORE TURNING ON THE SYSTEM FOR THE FIRST TIME, MAKE SURE THAT THE FIVE (SEVEN ON THE KX700.5) ROTARY CONTROLS ON TOP OF THE AMPLIFIER ARE TURNED FULLY COUNTER-CLOCKWISE!

GAIN CONTROL
Remember, the gain control is not a volume control, it matches the output of the head unit to the input level of the amplifier and must be adjusted properly for best performance. All the way up or down is not necessarily the best. Turn the head unit up to about 3/4 volume. (eg. If the head unit goes to 30, turn it to 25.) Next, turn (clockwise) the gain on the amplifier up slowly until you can hear audible distortion, then turn it down just a little. AMP 1 should be set first, then AMP 2 (KX700.5 only) and finally the SUB.

Crossover Control
Where you set the crossover is very subjective and can be fine tuned to match your listening preference or speaker requirements.

Bass Boost
The BASS BOOST control is designed to give you increased output at 40 Hz. The setting for this control is subjective, however, if you turn it up, you must go back and adjust the gain control to avoid clipping the amplifier.

1. Bass Boost Control 0 – 18 dB @ 40 Hz
2. Sub Input Gain Control 170mV – 5V & 340mV – 10V
3. Sub Crossover Control 50 – 200 Hz 12 dB/Oct
4. Amp 1 Gain Control 170mV – 5V & 340mV – 10V
5. Amp 1 Crossover Control 50 – 200 Hz 12 dB/Oc

1. Bass Boost Control 0-18 dB @ 40 Hz
2. Sub Input Gain Control High Level Low Level 170mV-5V 340mV-10V
3. Sub Crossover Control 50 Hz 200 Hz 12 dB/Oct
4. Amp 2 Input Gain Control High Level Low Level 170mV-5V 340mV-10V
5. Amp 2 Crossover Control 50 Hz-200 Hz 12 dB/Oct
6. Amp 1 Input Gain Control High Level Low Level 170 mV-5V 340mV-10V
7. Amp 1 Crossover Control 50 Hz-200 Hz 12 dB/Oct

Troubleshooting

If your amplifier does not appear to be working, check obvious things first such as blown fuses, poor or incorrect wiring connections, crossover and gain controls set incorrectly, etc.

There are two LEDs on the end panel of your Kicker KX series amplifier, one green and one red. When the green LED is lit this indicates the amplifier is turned on and no trouble exists. If the green LED turns off and the red LED is lit this indicates that the protection circuitry (SORT) is engaged.

The power indicator on top of the amplifier which illuminates the model badge follows the same function as the green LED.

 GreenLED off, nooutput:
Witha VoltOhmMeter(VOM) check:
Ö+12 volt power terminal (should read +12V to +16V).
ÖRemote turn-on terminal (should read +12V to +16V).
ÖGround terminal.

 GreenLED on, nooutput:
ÖCheck RCA connections.
ÖTest speaker outputs with known good speaker.
ÖSubstitute known good source unit.
ÖCheck for signal on RCA cable withVOM meter in AC position

RedLED on, nooutput:

1. Amp is very hot. ÖThermal protection is engaged. Check for proper impedance at speaker terminals. Also check for adequate airflow around amplifier.
2. Amp shuts down only while vehicle is running. ÖVoltage protection is engaged. Voltage to the amplifier is not within the 9-16 volt operating range. Have automobile charging/electrical system inspected.
3. Amp will only play at low volume levels. ÖShort circuit protection is engaged. Check for speaker wires shorted to each other or the vehicle chassis. Damaged speakers or operating below minimum impedance will also cause this.

 No out put from one channel:
Check balance control on head unit.
Check RCA & speaker connections for that channel.
Swap RCA connections from left to right.
If problem changes sides then you have a bad RCA cable or source unit problem.
Swap speaker connections from left to right. If problem changes sides then you have a bad speaker cable or bad speaker.

 Alternatornoise(whiningsoundthatvarieswithengineRPM):
Check for damaged RCA cable.
Check routing of RCA cable.
Check source unit for good ground.
Check gain setting, turn down if set too high.
 Poor stereo image reduce Basseterre spouse:
Check system phasing by turning the balance control from left to right. If there is more bass output when turned to either side then check your speaker wiring for proper positive and negative connections. reverse connections on one channel if necessary.

WARNING
KICKER drivers are capable of producing sound levels that can permanently damage your hearing! Turning up a system to a level that has audible distortion is more damaging to your ears than listening to an undistorted system at the same volume level. The threshold of pain is always an indicator that the sound level is too loud and may permanently damage your hearing. Pleaseusecommonsensewhencontrollingvolume!
