Cool running, lasts longer
The unique fin shape of the extruded aluminum heatsink helps pull heat away from the amp's interior, reducing distortion and extending the amp's life. An intelligent thermal management system continually monitors the temperature, saving your music from any interruptions due to overheating.

Features
CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4-ohm load, with 1% or less Total Harmonic Distortion (THD) plus noise, and over a frequency range of 20 Hz to 20 kHz, when applicable (20-200 Hz for this subwoofer amp). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. Using CEA-2006 criteria, the Kenwood X500-1 is rated at 300 Watts RMS x 1 channel with an 83 dBA signal to noise ratio.
Specifications: The manual also lists these non CEA-2006 compliant specifications:
- Power: 500 watts x 1-channel (into 2Ω, at 100 Hz, no more than 0.5% THD, 14.4 volts)
- Signal to Noise Ratio: 100 dB (at rated power)
Mono-Power Amp Design: The Kenwood X500-1 is designed with specific features to power your subwoofers with a frequency range between 20 and 200 Hz. This amplifier is not designed to power a full-range speaker.
Class D Amplifier Design: The amplifier design is Class D, which uses digital switching power supplies. The result is much higher efficiency (less heat generated) than Class AB.
Low-Pass Filter: The X500-1 has a built-in 24 dB/octave low-pass filter, continuously variable from 50 to 200 Hz. The crossover is always engaged (it cannot be bypassed).
Bass Boost: The bass boost circuit is centered at 40 Hz; boost is variable from 0 to +18 dB.
Aluminum Heat Sink: The aluminum heat sink increases the amplifier's heat dissipation efficiency, increasing the life of the amplifier.
Controls:
- Input Sensitivity: 200mV-5V
- Low-Pass Frequency: 50-200 Hz; continuously variable
- Bass Boost: 0-18 dB; continuously variable
Inputs and Outputs:
- Signal Input: one pair of RCA inputs
- Power: screw terminal; accommodates spade connector up to 0.54" wide
- Ground: screw terminal; accommodates spade connector up to 0.54" wide
- Remote Turn-on: screw terminal; accommodates spade connector up to 0.335" wide
- Speaker Output: one pair of screw terminals; accommodates spade connector up to 0.335" wide
- Fuses: two 30 amp ATO fuses

The Kenwood Excelon X500 (factory refurb.) is a great valued product. It performs and looks like it is brand new and met the demands of the 12" subwoofer I wanted to install. If I need to make a future amplifier purchase, I will definitely look for another factory refurbished one.
