INSTALLATION

Mounting: Choose a structurally sound location to mount your KICKER amplifier. 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 amplifier. Drill four holes using a 7/64" (3mm) bit and use the supplied #8 screws to mount the amplifier.

Wiring: The KXMA amplifier'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 amplifier using the KICKER KISL as shown. Alternatively, the signal can be delivered to the amplifier 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 amplifier. Use only KICKER KMPK Wiring Kits when installing or other genuine KICKER marine accessories when installing amplifiers in marine applications.

Model External Fuse

(sold separately)

KXMA900.5 1 x 100 Ampere 4 Gauge

Power/Ground Wire

POWER WIRING

For multiple amplifiers installations where distribution blocks are used, each amplifier should have its proper-rated fuse, or breaker, installed between the amplifier 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 amplifier'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 our ignition-protected Marine Rated Battery Fuses (MRBF) for these applications. 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.

FOUR CHANNEL OPERATION with SUBWOOFER minimum impedance of 2 ohm per channel (AMP1, AMP2) and 1 ohm for SUB channels)

BRIDGED OPERATION minimum impedance of 4 ohms bridged.
KICKER will now provide a three-year warranty with all KXMA-Series Amplifi er purchases paired with a qualifying KICKER Installation Kit*.

This extends the standard warranty by an additional year. Amplifier and Kit must be purchased from an Authorized KICKER Dealer.

KICKER KXMA amplifi er success is currently at an unheard-of rate, making the extended warranty program even more benefici dial to you.

Using poor-quality, under-spec wiring kits will impede KXMA amplifi er performance.

A superior-quality KICKER installation Kit is guaranteed to extend the life of KXMA amplifiers.

The new extended warranty applies only to KICKER amplifiers and accessories sold to consumers by Authorized KICKER Dealers in the United States of America or its possessions. It also only applies to the original purchaser of KICKER amplifiers and accessories. One warranty extension per amplifier is allowed regardless of the number of amplifier installation kits purchased. This program does not apply to "B"-stock product or factory-refurbished product.

This offer is for a limited time, so see your local Authorized KICKER Dealer soon for details.

Mini-USB for internal use only; do NOT remove or tamper. KICKER is not responsible for any damage to equipment resulting from connections made to this port.

Automatic Turn-On Selection: The KXMA series offers three different automatic turn-on modes that can be selected on the end panel; +12V, DC Offset, and Audio. Using either the DC Offset or Audio mode causes the REM terminal to have +12V out for turning on additional amplifiers.

• Remote Turn-On: Set the switch to +12V to use the remote turn-on lead from your source unit. Run 18 gauge wire from the Remote Turn-On Lead on your source unit to the terminal labeled REM between the amplifier's positive and negative power terminals. This is the preferred automatic turn-on method.
• DC Offset Turn-On: If Remote Turn-On is not an option, the next best setting is DC Offset. The DC Offset mode detects a 3V DC offset from the HI-Level speaker outputs when the source unit has been turned on.
• Signal Sense Turn-On: The Audio setting is the final alternative for Automatic turn-on. This is a Signal Sense turn-on method that detects the incoming audio signal from your source unit and automatically turns on the amp. This turn-on method will not work properly if the input gain control is not set appropriately.

Fader Switch: Depress the fader switch if you are running two sets of inputs (front and rear for example) to the amplifier. Leave the fader switch OFF if you want to drive all channels from a single stereo input.

Sub Input: If there is no dedicated output on your source unit for a subwoofer, use the SUB INPUT switch to set your subwoofer input to either SUB INPUT or AMP INPUT 2.

Input Gain Control with Gain Matching: The input gain control is not a volume control. It matches the output of the source unit to the input level of the amplifier and features Gain Matching to prevent clipping the input. For a quick setup, turn the source unit up to about 3/4 volume (if the source unit goes to 30, turn it to 25). KICKER recommends using the test tones at https://www.kicker.com/test-tones/ to reach the most accurate and best performing settings. Next, slowly turn (clockwise) the gain on the amplifier up until you see the Gain LED light up or hear audible distortion, then turn it down a little. If the GAIN knob's backlight comes on, the input is still clipping. For full instructions on Gain Matching, please see the next page.

Crossover Switches with Frequency Multiplier: Use the XOVER switches on the end panel of the amplifier to set the internal crossovers of AMPS 1 & 2 to OFF, HI-PASS, LO-PASS, or BAND-PASS (AMP 2 only). When the switch is set to OFF, a full bandwidth signal will be amplified. Set the switch to HP if you want the amplifier's internal crossover to serve as a high-pass filter. Set the switch to LP if you want the amplifier's internal crossover to serve as a low-pass filter. Set the switch to BP when a specific frequency range is required. Never change the crossover switches with the audio system on!

Set the 1X/10X frequency multiplier switch to the setting that is appropriate for your application. A setting of 10X will set the range of the AMP 1 crossover to 100-5,000Hz, and the LO-PASS crossover of AMP 2 to 400-5,000Hz.

Adjustable Subsonic Filter: The variable subsonic filter will provide a cut-off point for lower frequencies (10-80Hz) that could potentially damage your speakers from over-excursion, along with wasting your amplifier's power. The setting for this control should be set relative to your speaker's low-frequency capability. The setting for this control should be set relative to your speaker's low-frequency capability, and is recommended for ported enclosures.

KickEQ Bass Boost Control: The variable bass boost control on the side of the amplifier is designed to give you increased output, 0-6dB, at the selected frequency. The setting for this control is subjective. If you turn it up, you must readjust the input gain control to avoid clipping the amplifier.

Remote Bass-KMBLC: With the KMBLC remote bass level control, you have the ability to control the output level of the amplifier remotely. To surface-mount the KMBLC remote bass level control, simply screw the remote to the chosen location, then run the cable from the controller to the "Remote Bass" jack on the amplifier panel. Do NOT connect/disconnect while the amplifier is on. See page 8 for installation.

GAIN MATCHING

In any audio system, the goal is to reach maximum input and output levels without distortion or clipping. The engineers at KICKER have taken the guesswork, and hassle, out of matching the output voltage of your source unit to the amplifier with the Gain Matching feature. To begin, you'll need to download the KICKER test tones from www.kicker.com/test-tones. The following files are available in MP3 and WAV formats:

1kHz @ 0dBFS, 50Hz @ 0dBFS, 1kHz @ -10dBFS, 50Hz @ -10dBFS, 1kHz @ -5dBFS, 50Hz @ -5dBFS

These test tones are sine waves meant to provide a consistent signal for the KXMA amplifier to reference. The different recording levels are designed to give you the perfect gain match for your application.

0dBFS: Designed for audiophile applications to give you distortion free audio output with the most dynamic range.

-5dBFS: Designed for normal/daily applications, there will be less dynamic range but higher potential audio output levels. With this set up you can get some occasional clipping from the amplifier.

-10dBFS: Designed only for Subwoofer applications, there will be less dynamic range but higher potential audio output levels. With this set up you can get some clipping from the amplifier.

Afterwards, use the following procedure to accurately Gain Match your amplifi er(s):

1. Disconnect the speakers from the KXMA amplifier.
2. Set all EQ and crossover settings to flat on your source unit.
3. Play the downloadable file from KICKER.com
4. Tum the source unit up to 3/4 volume.
5. Increase the gain of the amplifier until the Gain LED turns on.
6. Decrease the gain of the amplifier until the Gain LED turns off.

GAIN GAIN MATCH

All level matching circuitry in the KXMA amplifiers is at the beginning of the signal chain. If you are going to use features like bass boost, SHOCwave or EQ settings, it may be necessary to readjust the gain to a lower setting to compensate for increased output at those frequencies.

Once the amp and source unit are gain matched, you will want to make certain you are not overdriving your speakers. Use the following procedure:

1. Set the source until volume to 0.
2. Reconnect the speakers to the KXMA amplifier.
3. Slowly increase the volume level of the source unit as you listen for audible distortion.
4. If you can hear clipping, decrease the gain of the amplifier until it is gone.

KMBLC REMOTE BASS INSTALLATION

Connect the cable to the KMBLC remote and the Remote Bass connection on the amplifier

TROUBLESHOOTING

If your amplifier does not appear to be working, check the obvious things first such as blown fuses, poor or incorrect wiring connections, incorrect setting of crossover switch and gain controls, etc. There is a Protection (PRT) LED on the side panel of your Kicker KXMA series amplifier. Depending on the state of the amplifier and the vehicle's charging system, the LED will either glow red or be off.

Red (PRT) LED flickering with loud music? The red (PRT) LED indicates low battery voltage. Check all the connections in your vehicle's charging system. It may be necessary to replace or charge your vehicle's battery or replace your vehicle's alternator.

Red (PRT) LED on, no output? ① Amplifier 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 airflow around the amplifier. ② Amplifier shuts down only while vehicle is running = voltage protection circuitry is engaged. Voltage to the amplifier is not within the 10-16 volt operating range. Have the vehicle's charging and electrical system inspected. ③ Amplifier will only play at low volume levels = short circuit protection is engaged. Check for speaker wires shorted to each other or to the vehicle chassis. Check for damaged speakers or speaker(s) operating below the minimum recommended impedance.

No or low output? Check the balance control on source unit Check the RCA (or speaker input) and speaker output connections.

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

Ground Noise? KICKER amplifiers 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. If you are experiencing this problem with your head unit, in most cases running a ground wire from the RCA outputs on the head unit to the chassis will remedy this issue.

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