Too often people forget that how you wire a sub to an amp is so extremely important to
the setup overall. Do it incorrectly and you can cause damage to the equipment or worse.
DVC subs always seem to confuse people for some reason. But let's treat them as just two
single coil subs instead. That seems to help people.
The most important thing about wiring subs to an amp is to make sure each path the power
can take is equal. Each branch should have the same mirrored branch to go with it so to
speak. Basically, you don't want power to have a lower resistance path to take or it will
not be a balanced setup. Here's an example. You have four subs and want to wire them to
an amp that has been determined to handle them. You can wire them all in series or all in
parallel (assuming the amp can take it) or you can do a combination like wiring two of them
together in series (two sets) and then each set together in parallel. That makes the overall
path the current can flow in each possible direction equal and the subs will get a balanced
division of the power.
So, to do that with DVC subs is simple. Remember each sub is essentially two subs so use
them as the series pair. On a 4-ohm DVC sub, this will make each sub represent 8-ohms and
then back at the amp, when the subs are wired together in parallel, they will return to 4-ohms.
Here is an electronic schema to give you a visual picture:
Notices:
A 4-ohm DVC sub by itself can never be wired up to show 4-ohms in one output. It can only be wired
in parallel to show 2-ohms or series to show 8-ohms.
