This outstanding amp boasts impressive power output, hands-on controls, and advanced digital features that redefine what an amplifier can do for your music.

Kenwood has been been blazing new trails in mobile audio for 25 years now, and they're celebrating with a series of special-design 25th Anniversary products. You can join the party with the 25th Anniversary XXV-02A 4-channel amplifier. This outstanding amp boasts impressive power output, hands-on controls, and advanced digital features that redefine what an amplifier can do for your music.

Under the glossy black exterior of XXV-02A, you'll find a quarter century of Kenwood amp-building experience. Aluminum electrolytic capacitors limit current leakage for long life and natural sound. A heavy-duty glass epoxy circuit board uses oversized circuit traces to handle high current with ease. High-speed output transistors, operating over an extremely wide frequency range, combine with fast-switching MOSFET power supplies and onboard cooling fans that keep the amp running cool and strong, even when the music is heating things up.

Along with 4 channels of power to drive your speaker setup, you get unprecedented control over every aspect of your sound — from the bass/treble balance to the bass frequency factor — all of which can be monitored from the amp's top-mounted blue LED display. Have an Excelon receiver in your car? If so, the Amplifier Management System (A.M.S.) puts the amp's advanced controls right at your fingertips, allowing you to make precise adjustments from the receiver's display.

Features

25th Anniversary: The Kenwood eXcelon XXV-02A amplifier is part of a special series of car stereo components to commemorate the 25th anniversary of Kenwood Car Electronics. These products are specially designed and tuned for superior audio performance. In addition, this amplifier features gold-plated input/output terminals, a glass epoxy circuit board, and a detachable brushed aluminum cover plate.

LED Status Display: The top-mounted LED display can be adjusted to show any of the following information:

  • Voltage: indicates the source voltage
  • Current: indicates the current consumption
  • Temperature: indicates the internal temperature
  • Fan: indicates the rotation speed of the cooling fan in 3 steps: Fast, Slow, or Off

Amplifier Management System (A.M.S.): The XXV-02A is compatible with 2004 or later Kenwood head units that feature an LX-Bus connection and the Amplifier Management System. When connected via a control cable (item #469KNWDIN) and standard S-Video cables (for 2-way remote operation), you can perform the following:

  • Daisy Chaining Amplifiers: Up to 7 additional A.M.S.-compatible Kenwood eXcelon amps can be connected together and controlled by the head unit. The "master" amp is assigned the ID # 0, and subsequent amps are assigned ID #s 1-7 to give you independent amp control.
  • Amp Adjustments: Using the display and menu control on the top of the amplifier, the following settings can be adjusted for each connected amplifier:
    • Bass Center Frequency: select 60Hz, 80Hz, 100Hz or 120Hz
    • Bass Gain: set between -15 and +15
    • Bass Q Factor: select between 1.00, 1.25, 1.50 and 2.00
    • Bass Extension: turn on or off; when on the low frequency response is extended by 20%
    • Treble Center Frequency: select 10kHz, 12kHz, 15kHz, or 17kHz
    • Treble Gain: set between -15 and +15
    • Volume Offset: adjusts the volume compared to other connected amps; set between -20 and 0dB
    • Temperature Mode: select display mode of temperature measurement between Fahrenheit or Celsius.
    • Default Values: resets all values to the initial (default) values
  • Display: The following can be displayed on the compatible head unit for each amplifier:
    • Amplifier Status: source voltage, current consumption, internal temperature (?F or ?C), rotation speed of cooling fan (Fast/Slow/Off)
    • ID Number: the ID number assigned to the amplifier you have selected
    • Error Status: When a connected amplifier fails, the amp number and the error status message are displayed

Variable Filters: The A and B channels have separate filters. The A channels have a high-pass filter that can be adjusted from 50 to 200 Hz, and has a slope of 12 dB per octave. The B channels have a filter that can be set for low-pass, high-pass, or full-range operation. In the low-pass and high-pass modes, the B-channel filter can be adjusted from 50 to 200 Hz. In the low-pass mode, the B-channel filter has a slope of 24 dB per octave, and in the high-pass mode, the B-channel filter has a slope of 12 dB per octave.

Infrasonic Filter: The B channels have an infrasonic filter that allows the amplifier to block ultra-low frequencies that your subs can't reproduce, improving the efficiency of your speaker system. The filter is fixed at 15 Hz, and has a slope of 24 dB per octave.

Preamp Outputs: The preamp output jacks provide a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the amplifier location. These outputs provide a full-range signal.

Quiet Turn-on: This feature allows the amplifier to power up over a period of several milliseconds instead of instantaneously, protecting your speakers from thumps and other sounds that could be damaging.

Protection Circuitry: To keep the amplifier safely operating, the protection circuitry is triggered in the following situations:

  • When a speaker wire may be shorted
  • When a speaker output contacts ground
  • When the unit malfunctions and a DC signal is sent to the speaker output
  • When the internal temperature is too high for the unit to operate
  • When the voltage is outside of the operating range

Controls, Inputs and Outputs

Controls: The amplifier controls are located on the top of the unit. The brushed aluminum plate can be removed to give you access to the control panel. The controls include:

  • B Channels:
    • LPF Frequency: rotary dial for setting the frequency of the B Channel's low pass filter (50-200Hz)
    • HPF Frequency: rotary dial for setting the frequency of the B Channel's high pass filter (50-200Hz)
    • Input Sensitivity: rotary dial for matching the preamp output voltage of the connected head unit (0.2 to 5.0 Volts)
    • Filter Switch: 2-way switch to set filter to high-pass or low-pass operation
    • Amp Control: 2-way on/off switch; On position allows you to control the sound with Amplifier Control, Off position bypasses the Amplifier Control circuit.
    • I.S.F.: 2-way on/off switch for the 15Hz infrasonic filter
    • Operation: 2-way switch to set the B channels to mono (Left input) or Stereo operation
  • A Channels:
    • HPF Frequency: rotary dial for setting the frequency of the A Channel's high pass filter (50-200Hz)
    • Input Sensitivity: rotary dial for matching the preamp output voltage of the connected head unit (0.2 to 5.0 Volts)
    • HPF Switch: 2-way switch to turn the high-pass filter on or off
    • Operation: 2-way switch to set the A channels to mono (Left input) or Stereo operation
  • ID Number Switch (located on front side of amp): rotary dial (slotted screwdriver required) for setting the Identification Number for amplifier control from a head unit

Inputs and Outputs: All of the inputs and outputs are conveniently located on the front side of the amplifier. The inputs and outputs include:

  • Fuses: Two 30-amp fuses
  • BATT (Power): gold-plated screw terminal (0.559" wide)
  • GND (Ground): gold-plated screw terminal (0.559" wide)
  • P.CON (remote turn-on): gold-plated screw terminal (0.345" wide)

  • To H/U (Head Unit): Round 13-pin jack for connecting control cable (item #469KNWDIN) to head unit for amplifier control
  • Remote: Two S-Video jacks for connecting slave amplifiers
  • Line Input: two pairs of gold-plated RCA inputs for B and A channels
  • Line Output: gold-plated RCA outputs (outputs signal from A channels)
