About the Kenwood KAC-7205
Kenwood Performance Series car amplifiers offer long-term reliability and superior sound quality in a compact, no-nonsense package. The KAC-7205 2-channel amp pumps out 170 watts RMS per channel to your components, or up to 500 watts RMS to a subwoofer in single-channel mode. A rugged cast-aluminum heatsink combines with two cooling fans to keep this amp running at optimal temperatures, even when you're pushing your system hard.
A built-in low-pass filter adjusts the output so you'll get the best sound possible from your subwoofer system. You can dial in up to 18 dB of bass boost to fatten up the sound.
An aluminum cover plate covers and protects the amp's controls and connections, giving your installation a professional look. Speaker-level inputs and signal sensing turn-on allow these amps to hook up to factory radios without preamp outputs.

MOSFET Switching Power Supply: The Kenwood KAC-7205 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: The KAC-7205's power ratings are measured according to the strict standards dictated by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the rated power output of all CEA 2006-compliant amplifiers, even if they come from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging.
Amplifier Rating: The Kenwood KAC-7205 two-channel amplifier is bridgeable (4-ohm), as well as 2-ohm stable in stereo.
- Two-Channel (CEA 2006 Compliant): 170 watts x 2 channel RMS @ 4 ohms (20 Hz-20 kHz, 1% THD)
- Two-Channel (2-ohm): 250 watts x 2 channel RMS (1 kHz, 0.08% THD)
- Bridged (4-ohm): 500 watts x 1 channel RMS (1 kHz, 0.08% THD)
- Peak Power: 500 watts x 2 channel (1,000 watts total max power)
Cast Aluminum Heat Sink: The Kenwood KAC7205 utilizes a cast aluminum heat sink design to ensure that the amplifier stays at its optimal temperature.
Fan Cooled: The KAC-7205 is equipped with two, rear panel-mounted cooling fans. One fan acts as an intake while the other serves as an exhaust to create a current of cooling air flowing through the inside of the amplifier.
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
Aluminum Cover Plate: The amplifier's controls and connections are hidden under a removable extruded aluminum cover plate. The cover plate provides a professional looking installing while helping to protect the amplifier's connections and control settings.
Blue/Red Illumination: The Kenwood two-channel amplifier features a blue and red LED illumination when the amplifier is turned on.
Signal-sensing Turn-On Circuitry: When the speaker-level input is used, it is not necessary to connect the power control wire (turn-on lead). The amplifier senses the signal from the speaker-level input and turns the amplifier power on automatically. Shortly after no signal is detected, the amplifier will automatically shut itself off.
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 (LPF): The Kenwood KAC-7205 is equipped with a variable low-pass crossover (24 dB/oct). The amplifier has a two-way filter switch, allowing you to choose low-pass (LPF) or full-range (Filter Off) operation. There is a rotary control for the Low Pass cutoff frequency, allowing you to set the LPF between 50 to 200 Hz.
Bass Boost: You can apply a bass boost of up to +18dB at 40Hz.
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-7205 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 gold-plated RCA line level inputs.
Speaker Level Input: The KAC-7205 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.
Fuses: The KAC-7205 is equipped with two 30 amp ATC blade fuses.
