The Kenwood brand name is associated with reliable audio equipment that is not going to cost the earth, but still delivers good quality sound. The company also produces solid, durable equipment that should last a long time. The Kenwood KAC-8406 is a sound system, intended for cars and trucks, that fits this bill perfectly.
The Kenwood KAC-8406 is a 4-channel system. With full-range speakers, the system delivers output of 70 watts RMS per channel, measured to CEA-2006 standards. However, if you want even more output volume, you have the option of switching the unit into 2-channel mode, and this boosts output to 200 watts per channel.
When used in 4-channel mode the system makes use of frequency filters on both the front and the rear channels to eliminate any interference from other electrical devices, or interference that can come from the motor. The filters also make it possible to install the unit almost anywhere without having to worry about performance degradation.
The Kenwood KAC-8406, is a sleek, stylish unit that measures 13-3/16″W x 2-1/4″H x 7-5/8″D. It is designed for self-installation, but does not ship with ground and power leads, so if you plan to install the system, you will have to acquire these separately. When assessing the performance of an amplifier, one of the problems is that the performance can be affected by the quality of the speaker system to which the amplifier is connected.
There is no doubt that the performance will be enhanced if the amplifier is used to boost the signal to top-grade speakers. However, the Kenwood KAC-8406 works quite well at boosting the sound quality of even medium grade speakers, the type that is often fitted as factory standard in many automobiles. That makes it a good choice for adding quality sound to a lot of in-car systems.
