This is the preferred automatic turn-on method. Run 18 gauge wire from the Remote Turn-On Lead on your source unit to the blue REM wire on the KEY amplifier’s wiring harness. Remote Turn-On: Set the switch to +12V to use the remote turn-on lead from your source unit.Using the DC Offset mode causes the REM wire to have +12V out for turning on additional amplifiers. The minimum impedance of 4 ohms per channel woofers must be installed to rear (AMP 2) channels tweeters must be installed to front (AMP 1) channelsĪutomatic Turn-On Selection: The KEY series offers two different automatic turn-on modes that can be selected on the end panel +12V and DC Offset. The primary power wire should also be fused between the battery and distribution block, within eighteen inches of the battery’s positive terminal, with a fuse or breaker rated at least to the sum of the individual amplifier’s fuse values, but doesn’t exceed the capacity of your wiring. If needed, cut off the RCA connections to use hi-level input.įor multiple amplifier installations where distribution blocks are used, each amplifier should have its proper-rated fuse, or breaker, installed between theĪmplifier and the distribution block within eighteen inches of the block, or on the distribution block if it provides for fusing. The KEY amplifier is capable of using the wiring directly from your head unit, but for best results, it is recommended you use power and ground wiring from the vehicle’s battery and chassis. 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. The fuse should be within 18” (45cm) of the battery and in-line with the harness’ power cable, which is connected to your amplifier. If you need to cross this wiring, cross it at a 90-degree angle.Ĭut the looped red power cable located in the KEY carton and install using the 20A fuse. Keep the audio signal cable away from factory wiring harnesses and other power wiring. Adding an additional ground wire of this same gauge (or larger) between the battery’s negative post and the vehicle chassis is recommended. Make the ground wire short, 24” (60cm) or less, and connect it to a paint-and-corrosion-free, solid, metal area of the vehicle’s chassis. Then connect the ground wire to the amplifier. It’s the best of all worlds, packed into a tiny powerhouse amp that delivers our signature KICKER Performance for your musical enjoyment.ĭisconnect the vehicle’s battery to avoid an electrical short.

You’ll experience symphonic quality music whether you’re using factory speakers and radio, or aftermarket products. With simple, one-step, automatic audio calibration, you’ll have drastically improved audio quality and soundstage in minutes. The KEY automatically improves the sound quality of your vehicle with the push of a button! Breathe new life and realism into any audio system with this small, yet powerful, amplifier and acoustic processor in one. PLEASE USE COMMON SENSE WHEN CONTROLLING VOLUME. THE THRESHOLD OF PAIN IS ALWAYS AN INDICATOR THAT THE SOUND LEVEL IS TOO LOUD AND MAY PERMANENTLY DAMAGE YOUR HEARING.
KICKER PRODUCTS 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. SUBWOOFERS SHOULD BE MOUNTED WITH AT LEAST 1 INCH (2.5CM) CLEARANCE BETWEEN THE FRONT OF THE SPEAKER AND ANY SURFACE. AMPLIFIERS REQUIRE UP TO 4 INCHES (10CM) OPEN VENTILATION. PROLONGED CONTINUOUS OPERATION OF AN AMPLIFIER, SPEAKER, OR SUBWOOFER IN A DISTORTED, CUPPED, OR OVER-POWERED MANNER CAN CAUSE YOUR AUDIO SYSTEM TO OVERHEAT, POSSIBLY CATCHING FIRE AND RESULTING IN SERIOUS DAMAGE TO YOUR COMPONENTS AND/OR VEHICLE. 13.1 Related Manuals / Resources Overview
