Specifications

Example 6:

System with separate amplifiers, one for the front system and one for the

subwoofers. The rear system is fed directly from the car stereo.

In this system the built-in amplifier of the car stereo is used for the front system through a 6 dB highpass-

filter with 200 Hz x-over. An active filter splits the signal between the rear and the sub amplifiers.

Suitable for: All DLS and GENESIS 2-channel amplifiers can be used in this example.

To DLS and GENESIS series 3 amplifiers you can use the internal filters instead of the Active filter.

Passive filters: To the rear system a 6 dB x-over (200 µF capacitor) with 200 Hz x-over frequency, 300

µF gives a x-over of 130 Hz, 150 µF gives 266 Hz.

Active filter: Use an active filter box to split the signal between front and sub system.

Disadvantages: There will be a great difference in sound quality between the rear system without

external amplifier, and the front system using a separate amplifier.

Amplifier load: Rear system: 4 ohms.

DLS SOUND HANDBOOK - AMPLIFIER WIRING EXAMPLES

NOTE! The subwoofers must never form an impedance lower than 4 ohms.

The mono bridge mode

connected sub should

have an impedance of 4

ohms.
