Default Simple sub volume control

i did a search for this topic but i didn't find anything, although im sure im not the first to ask this question:

i want to control the gain of my car amp from inside the car (the amp is in the trunk). Can i just wire a pot to the RCA cable and use that??? or will it create a buzz?

Radio Shack sells a stereo potentiometer that works great for this application. Part Number 271-1732.
