With one jumper in the middle on the bottom row it wires the coils in series.
The diagram would look like this
1. Using 1 set of terminals wire ther - to the - post of the amplifier
and the + to the + terminal of the amplifier.
2. This wiring show the amplifier a 2 ohm load.
With one jumper in the middle on the bottom row it wires the coils
in series.
The diagram would look like this
Using the jumper block - both coils in series:
With the cone facing upward and the jumper block in front of you,
the positive terminal on the terminal block on the left side would
be positive and the negative terminal on the right side would be
negative. The negative on the left terminal and the positive on the
right terminal are shorted together and not used.
