Kenwood XR-S17P manual Amplifiers, Honey, I Shrunk the Amps, Class D Prize Fighters

AMPLIFIERS

Amplifiers go a long way in improving the overall performance of any audio system, and Kenwood is the leader in amp technology. With gas prices climbing, smaller, more fuel-efficient vehicles are working their

way into the install bay—good for the environment (hooray!), hard on the mobile electronics specialist trying to squeeze in an amp or two.

Fortunately, Kenwood is ahead of the game with a new line of amps that are potent and remarkably small.

Different Amps for Different Systems

eXcelon and Kenwood offer different amplifiers to fit any vehicle and system configuration:

Class D Mono Power Amp: Designed for subwoofers, Class D amps offer big power and are less demanding on electrical systems.

Class D 4-channel Amp: This digital 4-channel amp is small, efficient, and produces high power. Use this to run all your full range speakers.

Class A/B 4-channel Amp: This amp is flexible and can be used to run four full range speakers or a sub and two full range speakers.

Class A/B 2-channel or Stereo/Bridgeable Amp:

A great amp for a pair of front speakers, or bridge it to a subwoofer.

Honey, I Shrunk the Amps

New Kenwood amps pack power into a much smaller chassis size—up to 44% smaller than previous models—and include the KAC-9104D and KAC-8104D Class D Mono power amps, the KAC-8404 4/3/2-channel power amp and the KAC-7204 stereo/bridgeable amp.

These amps are a serious break-through in technology, but how did we squeeze all that juice into a smaller chassis? For starters, engineers moved the transistors and fixed them directly to the heat sink, which helps dissipate heat better. They also expanded the path of airflow by going from one larger fan to two smaller ones. Two fans mean two paths of airflow, which dramatically improves distribution of cool air. This and other design evolutions result in amplifiers as powerful as their bigger ancestors but smaller and more adaptable to new environments.

You’ll also notice a redesigned cover with blue illumination that looks great installed, and we’ve added signal sensing turn-on and bass boost control to all four models.

Class D Prize Fighters

The KAC-9104D and KAC-8104D are 30% and 33% smaller than last year’s models. The KAC-9104D is 500 Watts X 1 @ 4 ohms and is 1-ohm stable. The KAC-8104D is 300 Watts x 1 @ 4 ohms. Key features of both include built-in variable low-pass filter, built-in infrasonic filter, signal sens- ing turn-on, blue illumination, speaker level input, and bass boost (up to +18 dB of boost at 40Hz).
