Number Impedance
of woofers to amplifier
1 Connect individual voice coils to individual amplifier channels. 3 ohms
2 Connect the two coils of each woofer in parallel and connect 1.5 ohms
each woofer to an amplifier channel
3 Connect the coils of each woofer in series, connect the three 2 ohms
woofer in parallel, and connect to bridged amplifier channels
4 Connect one coil from each of two woofer in series. Connect 4 ohms
the remaining coils of the same two woofers in series.
Connect the first and second coil pairs in parallel, and
connect to an individual amplifier channel. Repeat for the
second channel using the second two woofers.
