[Jukebox-list] Drive-In Speakers

[etreble7]

Good Morning,
Quick question about the volume pots for the Drive In Movie Speakers I restored.  Below is a discription of the speakers :

Product Details:

All models feature paper cones with weather resistant foam surround, and a "wizzer" cone for extended high frequency response. Intended for direct replacement, these models include no mounting hardware, grills or speaker wire. Sold individually. 

Features: Specifications: 
a.. Power capacity: 10W RMS 
a.. Impedance: 4ohm 
a.. Connections: Male tab 3/16" positive, 1/8" negative Frequency MagnetMounting 
My question is what wattage pots should I use (these were replaced by a friend and they don't adjust, they are just either ON or OFF.  )  I want to order the correct ones and replace what he put in.  I hope this is enough information, thanks in advance,

a.. Jackie
