Not quite sure what you mean by a 4-way connection, but...
Either you use a 2 wire ("normal" speaker wire) connection with the jumpers, or you remove the jumpers and use a 4 wire bi-wire connection.
If you are going to bi-amp the speakers, then the jumpers MUST be removed or it's very likely your amplifier/receiver will be damaged.
