About the Kenwood KAC-5204
Kenwood amplifiers have earned a strong reputation for rugged, no-nonsense reliability and superior sound quality. They feature efficient power supplies and beefy internal components so they'll pump up a ton of clean, crisp sound at a great price.
The 2-channel KAC-5204 amp delivers 60 watts RMS per channel to your full-range speaker system, which will really improve your sound quality dramatically. This tough little amp will bring new life to your factory speakers, but you'll really notice the difference when you pair it with new aftermarket speakers. You'll hear all the tonal color, depth, and detail you've been missing, whether it's the slide of a finger on an acoustic guitar, or the subtle tones of your favorite singer's voice.
You can also run the KAC-5204 in mono mode to provide 150 watts of RMS power to a subwoofer. In addition to the RCA preamp inputs, you'll find handy speaker-level inputs that allow the amp to work in just about any kind of system.

Features
MOSFET Switching Power Supply: The Kenwood KAC-5204 Two-Channel amplifier is equipped with a MOSFET switching power supply. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise.
CEA-2006 Compliant: CEA-2006 is a new system of testing & 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 at a frequency range (for full range 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. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. The Kenwood KAC-5204 under CEA-2006 regulations is rated at 60 Watts RMS x 2 channels with a 75 dBA signal to noise ratio.
2-Ohm Stable: The amplifier can support a 2-ohm stereo load. The amplifier is rated at 75 watts RMS x 2-channel in 2-ohms.
Bridgeable: The two-channel amplifier can be bridged for a mono 4-ohm load. The amplifier is rated at 150 watts x 1-channel RMS when bridged.
Cast Aluminum Heat Sink: The Kenwood KAC-5204 utilizes a cast aluminum heat sink design to ensure that the amplifier stays at its optimal temperature.
Protection circuitry: The amplifier features protection circuits that will turn the amp off in case of the following events:
- Speaker output contacts ground.
- Speaker wire short-circuits.
- Unit malfunctions and DC is sent to speaker output.
- Internal temperature is too high.
- Loss of ground of head unit or amp.
Power Indicator: When the power is turned on to the amplifier, the Power indicator (on top of the amp) will light up red. This indicator will turn off with the amplifier and will turn off if the amplifier goes into protect mode.
Controls
Gain: To accommodate the varying range of signal levels coming from today's factory and aftermarket radios, the Kenwood KAC-7205 features an adjustable gain control (0.2-5.0V). This means that no matter what kind of radio is connected to this amplifier, the appropriate gain control adjustment can be made to ensure loud, clear, distortion-free music.
Low Pass Crossover: The amplifier features a fixed 80Hz (-12dB/oct) low-pass filter which can be turned On or Off.
Connections
Power Connections: The power and ground connections are 0.5625" wide screw terminals that will accommodate up to 4-gauge wire. The remote turn-on terminal is 0.3125" wide and will accept up to 8-gauge wire. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Spade connectors are recommended for the power, ground, and remote wires.
Speaker Outputs: The Kenwood KAC-5204 is equipped with two pair of speaker terminals. All four speaker terminals are 0.3125" wide screw terminals and will accommodate up to 8-gauge wire. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Spade connectors are recommended for the speaker wires.
Note: The speaker output terminals can be used in stereo or bridged mode.
Line Level Input: The two-channel amplifier is equipped with a pair of RCA line level inputs.
Speaker-level input: Multi-pin input for use with included speaker level input harness The KAC-5204 comes with a two channel speaker level input harness. Once you splice the speaker wires from the receiver to the harness, you have plug-in convenience to the amplifier. This feature makes it easier to add an amplifier to a factory radio or to a receiver with no preamp outputs. The maximum power output from the source receiver can be no more than 40 watts.
Fuse: The amplifier is equipped with a 25-amp ATC fuse.

It just works... Wasn't looking for a high end amp. Just needed something to give the front component speakers enough power to perform well. Simple install, easy to adjust, and small enough to put almost anywhere.
