On DLS mono amplifiers, with dual speaker connectors,
both the + and - terminals are internally connected in
parallel.
CAD11 and CAD15 has a speaker terminal different
from this illustration, but we hope you understand what
we mean.

Connection of two subwoofers
with 4 ohm dual voice coils in
parallel and then in series to the
amplifier with a resulting
impedance of 4 ohms.
If you connect two subwoofers with
2 ohm voice coils in this way the
resulting impedance is 2 ohms.
