Parallel operation
Two subwoofers with one voice coil (single voice coil)
or one subwoofer with dual voice coil are connected in
parallel.
Note:
The parallel connection of two voice coils will
result in halving the impedance!
Maximum output power of this configuration:
Two subwoofers with 1 x 4 Ohms
correspond to a total
impedance of 2 Ohms: 675 / 1350 Watts
One subwoofer with 2 x 4 Ohms
also corresponds to a
total impedance of 2 Ohms: 675 / 1350 Watts
Two subwoofers with 1 x 2 Ohms
correspond to a total
impedance of 1 Ohm: 920 / 1840 Watts
One subwoofer with 2 x 2 Ohms
also corresponds to a
total impedance of 1 Ohm: 920 / 1840 Watts
Note:
The parallel connection of 1 Ohm voice coils will
result in shutdown of the amplifier.

In series
Two subwoofers with one voice coil (single voice coil)
or one subwoofer with dual voice coil are connected in
series.
Note:
The connection of two voice coils in series will re-
sult in doubling the impedance!
Maximum output power of this configuration:
Two subwoofers with 1 x 2 Ohms
correspond to a total
impedance of 4 Ohms: 390 / 780 Watts
One subwoofer with 2 x 2 Ohms
also corresponds to a
total impedance of 4 Ohms: 390 / 780 Watts
Two subwoofers with 1 x 1 Ohm
correspond to a total
impedance of 2 Ohms: 675 / 1350 Watts
One subwoofer with 2 x 1 Ohm
also corresponds to a
total impedance of 2 Ohms: 675 / 1350 Watts
Note:
The connection of subwoofers with 4 Ohms in
series results in a low output power of the amplifier!
