DUAL DRIVE
Dual Drive derives from the shape of a speaker driven by two amplifiers with a feedback circuit. The new KAC-PS1D provides a bridged output free of the noise caused by power supply fluctuation since there is no pumping phenomena.

DUAL POWER SUPPLY
Kenwood includes a newly adopted choke coil for achievement of dynamic sound and powerful bass. The transformers supply power separately to the positive load and negative load, thereby stabilising the power supply.

FULL CONTACT TERMINAL
New terminal blocks are adopted on KAC-PS1D and KAC-PS4D. The unique configuration of the terminal plate helps provent connection wire disconnection. These models reduce wire damage since the connection wires are pressed flatly to the surface plate.

KAC-PS4D FULL FUNCTION DSP (DIGITAL EQ & X’OVER)
A Full function DSP gives Parametric EQ and Crossover function. This enables the user to input detailed information and set a variety of functions according to the type of vehicle driven. The settings are carefully chosen by incar measurements, and you can even create the best audio atmosphere by pressing the DELAY button.

DOWNSIZED USING DIGITAL TECHNOLOGY
Kenwood introduces a smaller sized heat sink for its digital amplifiers, making it possible to install in any vehicle. It even gives it a better, more stylish appearance. See below.
