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.
CONNECTION OF SUBWOOFERS IN
BRIDGE MODE TO DLS STEREO AMPS
On DLS mono amplifiers, with dual speaker connectors, both the + and - terminals are internally connected in parrallel.
