Item #000119Kenwood KAC-8405 4/3/2 Channel Power Amplifier, 720 ..


Kenwood KAC-8405 4/3/2 Channel Power Amplifier, 720 WATTS


The KAC-8405 4-channel amplifier is 44% smaller than our previous year model and still cranks out 600 Watts of pure power. This tiny but mighty amp will fit in tight places and is ideal for bumping up the performance of front and rear speakers.

•    600 Watts of Power with 44% Smaller Chassis Size
•    CEA Rated: 50W (1.0% THD+N) (4Ohm/4Ch)
•    CEA Rated: 75W (1.0% THD+N) (2Ohm/4Ch)
•    High Quality Speaker Level Input and Blue Illumination
•    High-pass (12 dB per octave) and low-pass (24 dB per octave) filters variable from 50 to 200Hz
•    Variable Bass Boost control (0-18 dB at 40 Hz)
•    Cooling fan
•    MOSFET power supply
•    Speaker-level inputs with signal sensing turn-on
•    11-1/16"W x 2-5/16"H x 9-7/8"D


In 2003, the Consumer Electronics Association established standard CEA-2006, "Testing & Measurement Methods for Mobile Audio Amplifiers." This "voluntary" standard advocates a uniform method for determining an amplifier's RMS power and signal-to-noise ratio. Using 14.4 volts, RMS watts are measured into a 4-ohm impedance load at 1 percent Total Harmonic Distortion (THD) plus noise, at a frequency range (for general purpose amplifiers) of 20 Hz to 20,000 Hz. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms.
