To avoid short-circuiting the speakers
Make sure the stripped end of each speaker cord does not touch another
speaker terminal or the stripped end of another speaker cord.
Examples of poor connection of the speaker cord
Stripped cords are touching each other
due to excessive removal of insulation.
Stripped speaker cord is touching
another speaker terminal.
Note:
Be sure to match the speaker cord to the appropriate terminal on the
components: + to + and - to -. If the cords are reversed, the sound will be
distorted and will lack bass.
Skill of connecting speaker wires:
1. Push down the Speaker terminal tab down to insert wire.
2. Push up the Speaker terminal tab to lock wire in the terminal.
3. Make sure the insulation is completely removed from the ends of the speaker
