potentiometer to control volume?

[LKJR]

Working on the audio layout for the boat, as of right now it's 2 sets of 6.5's in the cockpit then a set of somethings in the cuddy cabin. What I'd like to do is find a way to shut off all the speakers in the cockpit and run just the ones in the cuddy. I'm amping all the speakers so I could just switch all the signal wires so I can shut them off but how about seperate volume control for the cabin? Dont remember if it's a reostat or a potentiometer that I"d use? But wouldn't that affect hte ohm load the amp sees? Worried if I use that route that I'd fry the amp.

Sounds like you want an L-pad (potentiometer). We use ones from parts express. Call them and they will tell you which ones you need for you impedance.

is impedance what I want to control the volume? and whouldn't that affect the ohm load the amp sees?

how will changing the impedance not affect the load on the amp?
