I am new to this site and apologise if I am in the wrong area!

I have fitted a pair of extension speakers in another room and want to be able to control their volume in that room rather than from the original stereo unit.

Is this simply a matter of wiring in a variable resistance or do I need more 'bits' to go with it?

Ideally, you need a special type of variable resistor (potentiometer) called an "L-pad" that presents a constant impedance to the amplifier.
Otherwise a normal, although high wattage potentiometer will do it OK; you will need a *BIG* potentiometer if you plan on having the amplifier turned up high, and reducing the volume locally.
