Wiring your subs: Dual Voice Coils |
|
|
|
With multi-driver sub systems, which
often feature dual voice coils (DVC) on each driver, the level of
wiring complexity can be enough to turn-off even the most adventurous
of car audio do-it-yourselfers. Fear not though, for we have compiled
wiring diagrams of several configurations for dual voice coil
(DVC) drivers.
Please note that when wiring multiple drivers it is recommended that
series connections between drivers be avoided at all costs. This does
not include series connections made between voice coils on the same
driver. For more information, please consult our dual voice coil tutorial.
Additionally, if you have an idea for a wiring configuration and you do
not see it here, chances are you should re-think its implementation (in
other words, don't do it). You will more than likely find that the
results will be less than optimal.
