INSTALLATION

Mounting: Choose a dry, structurally sound location to mount your KICKER amplifi er. Make sure there are no items behind the area where the screws will be driven. Choose a location that allows at least 4” (10cm) of open ventilation for the amplifi er. Drill four holes using a 7/64” (3mm) bit and use the supplied #8 screws to mount the amplifi er.

Wiring: The KMA amplifi er’s RCA inputs will receive either high or low level signals from your car stereo’s source unit. A high-level signal can be run from the source unit’s speaker outputs to the stereo RCA input on the end panel of the amplifi er using the KICKER KISL as shown (see page 3). Alternatively, the signal can be delivered to the amplifi er using the low- level RCA outputs on the source unit. Keep the audio signal cable away from factory wiring harnesses and other power wiring. If you need to cross this wiring, cross it at a 90 degree angle.

Install a fuse within 7” (18cm) of the battery and in-line with the power cable connected to your amplifi er.

For multiple amplifi er installations where distribution blocks are used, each amplifi er should have its proper-rated fuse, or breaker, installed between the amplifi er and the distribution block within seven inches of the block, or on the distribution block if it provides for fusing. The primary power wire should also be fused between the battery and distribution block, within seven inches of the battery’s B+ terminal, with a fuse or breaker rated at least to the sum of the individual amplifi er’s fuse values, but not to exceed 1.5-times the sum of the individual fuse values (not to exceed the ampacity of the thermal insulation of the wiring as shown in U.S.C.G. CFR33 183.425, Table 5). KICKER recommends using the KICKER marine line of power distribution accessories. These are fully marine compliant with ignition protected fuses and meet all USCG standards. Pair a KMFMF master fuse holder for your main power with a KMFDB3 and KMDB3 fused power and ground distribution blocks for the ultimate in protection for your boat! See the diagram below.

NOTE: Seven inches is the standard distance under U.S. Coast Guard CFR33 for placement of fuses or breakers as required by law for new boat manufacturing. We recommend trying to adhere to this standard in a consumer installation. Failure to do so does not mean you are breaking the law, but it does put the safety of your boat and passengers at risk in the event of a power wire short circuit.

OPERATION

Automatic Turn-On Selection: The KMA series offers two different automatic turn-on modes that can be selected on the end panel; +12V and DC Offset.

• Remote Turn-On: Run 18 gauge wire from the Remote Turn-On Lead on your source unit to the blue REM wire on KEY amplifi er’s wiring harness. This is the preferred automatic turn-on method.
• If 12V remote turn-on is not available, DC Offset turn-on can be used if speaker-level (high-level) audio inputs are being used. The DC offset mode detects a 6V DC offset on the speaker wires when the source unit has been turned on.

Input Level: The RCA inputs on KICKER KMA amplifi ers are capable of receiving either Hi or Low-level signals from your source unit. If you are using a Hi-Level signal, simply press in the Input Level switch on the amplifi er. Refer to the wiring section of this manual for additional instructions.
Crossover Control: The variable crossover on the side of the amplifi er allows you to adjust the crossover frequency of AMP3 (KMA600.6 only) to OFF, hi-pass, or lo-pass from 50–200Hz, and the hipass crossover frequency of AMP1 & AMP2 from OFF-200Hz. OFF will pass a full-range signal, HI will cut
off frequencies below a threshold, and LO will cut off frequencies above a threshold.
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 amplifi er. 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 amplifi er up until you can hear audible distortion, then turn it down a little.
Bass Boost Control: The variable bass boost control on the side of the amplifi er is designed to give you increased output, 0–6dB, at 40Hz. The setting for this control is subjective. If you turn it up, you must readjust the input gain control to avoid clipping the amplifi er.

TROUBLESHOOTING

If your amplifi er does not appear to be working, check the obvious things fi rst such as blown fuses, poor or incorrect wiring connections, incorrect setting of crossover switch and gain controls, etc. There are Power (PWR) & Protection (PRT) LEDs on the side panel of your Kicker KMA series amplifi er. Depending on the state of the amplifi er and the vehicle’s charging system, the LEDs will glow either green or red.
When the green LED is lit, this indicates the amplifi er is turned on and no trouble exists.

Green LED off, no output? With a Volt Ohm Meter (VOM) check the following: n+12 volt power terminal (should read ❶+12V to +16V) ❷Remote turn- on terminal (should read +12V to +16V) ❸Check for reversed power and ground connections ❹Ground terminal, for proper conductivity

Green LED on, no output? Check the following: ❶RCA connections ❷Test speaker outputs with a “known” good speaker. ❸Substitute source unit with a “known” good source unit. ❸Check for a signal in the RCA cable feeding the amplifi er with the VOM meter set to measure  “AC” voltage.

Red LED fl ickering with loud music? The red LED indicates low battery voltage. Check all the connections in your boat’s charging system. It may be necessary to replace or charge your battery or replace your alternator.

Red LED on, no output? ❶Amplifi er is very hot = thermal protection is engaged. Test for proper impedance at the speaker terminals with a VOM meter (see the diagrams in this manual for minimum recommended impedance and multiple speaker wiring suggestions). Also check for adequate airfl ow around the amplifi er. ❷Amplifi er shuts down only while your boat is running = voltage protection circuitry is engaged. Voltage to the amplifi er is not within the 10–16 volt operating range. Have the boat’s charging and electrical system inspected. ❸Amplifi er will only play at low volume levels = short circuit protection is engaged. Check for speaker wires shorted to each other. Check for damaged speakers or speaker(s) operating below the minimum recommended impedance.

No or low output? ❶Check the balance control on source unit ❷Check the RCA (or speaker input) and speaker output connections. ❸Check for reversed polarity at the speaker(s)

Alternator noise-whining sound with engine’s RPM? ❶Check for damaged RCA (or speaker input) cable ❷Check the routing of RCA (or speaker input) cable ❸Check the source unit for proper grounding ❹Check the gain settings and turn them down if they are set too high.

Ground Noise? KICKER amplifi ers are engineered to be fully compatible with all manufacturers’ head units. Some head units may require additional grounding to prevent noise from entering the audio signal.

CAUTION: When jump starting the battery, be sure that connections made with jumper cables are correct. Improper connections can result in blown amplifi er fuses as well as the failure of other critical systems in the boat.
