Connecting speakers

Conventional

The 2 terminals of the amp are connected with the corresponding terminals of the speakers.

Bi-wiring

Today a lot of speakers do have 2 sets of terminals bridged by a jumper.
Remove the jumpers and run separate cables from amp to the speaker terminals.

A bit more on bi-wiring.

There are alternatives like bi-amping and active crossovers.

This is covered in more detail here.
