Wiring Guidelines - Image Dynamics USA IDQ V4 Series Owner's Manual

WIRING GUIDELINES

It is highly recommended that you seek an authorized Image Dynamics dealer to properly
setup, wire and install your woofers for maximum performance.
There are multiple ways to wire your woofers depending on your amplifier and system
configuration. The use of multiple voice coils offers you more versatility in system con-
figuration. It is important to know the limits of your amplifier to optimize its performance.
It is always better to use your subwoofer in a mono / bridged mode if your amplifier has
the capabilities. There are basically four different types of wiring configurations: Series,
Parallel, Series-Parallel or Parallel-Parallel. It is possible to change the impedance or load
by how the speakers are to be wired and by the quantity of woofers used.
