Introduction KX2500.1 Amplifier Owner’s Manual KX2500.1 Mono-Block Model: Attention: Congratulations! Please record your purchase information in the area provided below. We recommend attaching the original sales receipt or a copy of it to this manual for future reference. You have just purchased the latest in amplifier technology to carry the famous KICKER name. Your KICKER KX2500.
Class D Mono Amplifier Delivers massive power into a PAST (PRE Amp Signal Transfer) Output RCA jacks to pass the single channel with greater efficiency than conventional class A/B amplification. incoming signal to another amplifier or component. Low Impedance Operation Designed for stable operation maximum power transfer and clamping. Features Features Custom tooled gold plated connectors Assure and maximum power output into a 2 ohm load.
Installation Mounting Remove Remove When selecting a location to mount your Kicker amplifier be sure it is structurally sound and that there are no items behind the area that could be damaged by the screws. Check for wiring 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.
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. Connecting to the amp with either input will provide a low level signal at the output (PAST) jacks.

Installation BIG AMP AHEAD Just in case you missed it at the time of purchase, this is a BIG amplifier that will create BIG power. For an amplifier to produce 2500 watts of output power it requires a solid electrical system feeding it and a solid delivery system to your speakers. What this means is you have to use the appropriate wire and accessories with this amplifier to insure optimum performance and durability. We recommend using Genuine Kicker Installation Accessories.
Installation System Diagrams The following diagrams shows the most common configurations for your Kicker KX2500.1 series amplifier. MONO CHANNEL OPERATION The KX2500.1 amplifier is capable of operating into a minimum impedance of 2 ohms (Ω). If you are using a single voice coil woofer be sure the impedance of the voice coil is equal to or greater than 2Ω. If using dual voice coil subwoofer or driving multiple subwoofers, be sure the net impedance presented to the amplifier is at least 2Ω or greater.
Installation TWO KX2500.1 AMPLIFIERS & ONE DVC SUBWOOFER This diagram shows how to power a single Dual Voice Coil (DVC) subwoofer using two KX2500.1 amplifiers. For maximum power output from your KX2500.1 to the subwoofer each voice coil should be 2Ω impedance. Do not connect to voice coils with an impedance lower than 2Ω! Be sure to properly power and ground each amplifier according to the minimum specifications shown on page 6 to insure proper operation and maximum power output.
Installation ONE SUBWOOFER For maximum power into a single subwoofer you will need a 2Ω Single Voice Coil (SVC) subwoofer OR a 4Ω Dual Voice Coil (DVC) subwoofer. Single 4Ω DVC - Parallel Wired Single 2Ω SVC Coil 2 + Coil + Coil 2 - Coil 1 - + + Coil - Coil 1 + TWO SUBWOOFERS For maximum power into a pair of subwoofers you will need two 4Ω Single Voice Coil (SVC) subwoofers OR two 2Ω Dual Voice Coil (DVC) subwoofers.
Installation FOUR SUBWOOFERS For maximum power into a quad set of subwoofers you will need four 8Ω Single Voice Coil (SVC) subwoofers OR four 4Ω Dual Voice Coil (DVC) subwoofers. Four 8Ω SVC - Parallel Wired Coil + Coil + Coil + Coil + + Coil - Coil - Coil - Coil - Four 4Ω DVC - Series/Parallel Wired 10 Coil 1 + Coil 1 + KX2500.
The Output (Pre Amp Signal Transfer) RCA jacks allow you to send the incoming signal from one Kicker KX2500.1 series amplifier to another amplifier or processor without the need for Y cables. The signal from the PAST jacks is identical to the signal fed to the amplifier via its RCA input jacks or the High Level inputs and is not affected by the amplifier’s built in crossover. Mounting Surface Most head units with high voltage outputs should be capable of driving up to ten amplifiers in a chain.
Navigation Operation Your Kicker amplifier has three rotary controls on top and one switch on the end panel. These controls ensure the reliability and performance of the amplifier, so they need to be set correctly. SUBSONIC FILTER SWITCH NEVER CHANGE THE SUBSONIC FILTER SWITCH SETTING WITH THE SYSTEM ON! The switch located on the end panel next to the RCA jacks is for the subsonic filter. It is 12db/octave set at 25 Hz.
Trouble shooting Help If your amplifier does not appear to be working, check obvious things first such as blown fuses, poor or incorrect wiring connections, gain controls properly set, 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.
