How do you hook up speaker wire to a speaker?

Each speaker needs to be connected using two wires. One wire is "grounded" and the other carries the alternating sound signal. This question is very simple to ask but is much more complicated to answer because you don't say anything about the kinds of terminals there are on the speaker or the amplifier! On the speaker are there threaded posts with thumb nuts? Or clip-on-wire connectors? Or some other system? On the amplifier what type of speaker output terminals are there: are they screw-down types which need a loop of wire under a washer? Or sockets for phono plugs? Or some other system?

There are so many possible wire/terminal combinations it doesn't make sense to write a long essay on all the possible hook-ups you could use.

If you cannot work it out from the User Guides that came with the speaker or the amplifier then it is best either to ask a friend who knows about speakers to show you what to do, or ask someone at any store that sells hi-fi systems.
