User manual AUDIO DESIGN IX500.4

[. . . ] Ideally, when connecting the source unit to the amplifier, the IX amplifier's input level switch should be set to "LO" and a low-level signal should run from the source unit's stereo RCA output to the stereo RCA input on the end panel of the amplifier using RCA interconnect cable. If a low-level stereo RCA output is not available on the source unit, the signal can be delivered to the amplifier using the high-level speaker outputs on the source unit. set the input level switch on the end panel of the amplifier to "HI". Crimp and solder RCA connectors to the end of the speaker wire running from the high-level speaker outputs on the source unit and connect the wire to the RCA Inputs on the end panel of the amplifier or simplify the installation by using a KICKER ZISL as shown below. [. . . ] 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 an illuminated blue badge on top of the amplifier denoting the power state of the amp in addition to the Protection LED on the end panel of your KICKER IX series amplifier. When the blue badge is lit, this indicates the amplifier is turned on and the amplifier is functioning properly. With a Volt Ohm Meter (VOM) check the following: +12 volt power terminal (should read +12V to +16V) Remote turn-on terminal (should read +12V to +16V) Check for reversed power and ground connections. Check the following: RCA connections Test speaker outputs with a "known" good speaker. It may be necessary to replace or charge your vehicle's battery or replace your vehicle's alternator. 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). Amplifier shuts down only while vehicle is running = voltage protection circuitry is engaged. Amplifier will only play at low volume levels = short circuit protection is engaged. Check the balance control on source unit Check the RCA (or speaker input) and speaker output connections for the channel Swap the RCA (or speaker input) cable from left to right. If the problem changes sides then you have a bad RCA (or speaker input) cable or source unit problem. If the problem changes sides then you have a bad speaker cable, passive crossover network and/or speaker. 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. 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, passive crossover networks and speaker terminals for proper positive and negative connections. Reverse a speaker connection from positive to negative on the stereo/subwoofer channel(s); if the bass improves, the speaker was out of phase. When using both sets of low-level (RCA) or high-level (speaker wire) inputs, the fader button must be pushed in. 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. Please Note: Modern high performance speakers have a lower DC Resistance than what used to be available. The KICKER Coaxial and Component speakers are rated at four ohms (some DC Resistances may be as low as 3 ohms) and work with any amplifier designed to operate at a four ohm load. [. . . ] WHAT TO DO IF YOU NEED WARRANTY OR SERVICE: Defective merchandise should be returned to your local Authorized Stillwater Designs (KICKER) Dealer for warranty service. You can confirm that a dealer is authorized by asking to see a current authorized dealer window decal. If it becomes necessary for you to return defective merchandise directly to Stillwater Designs (KICKER), call the KICKER Customer Service Department at (405) 624-8510 for a Return Merchandise Authorization (RMA) number. Package only the defective items in a package that will prevent shipping damage, and return to: Stillwater Designs, 3100 North Husband St, Stillwater, OK 74075 The RMA number must be clearly marked on the outside of the package.
