Default Volume Control Problem

I have a alps blue 100k volume pot.

I hooked it up the way the manufacture says but when I turn the knob it changes the tone balance from low to high and does not effect output level.

Just to be clear I think I should be able to put a Ipod input directly into the pot and the output to my amp and it should attenuate the level, right? Just want to make sure I am not missing something obvious.

Or do you guys have a better simple solution to control the volume before my amp?

Here is a diagram of my set up showing the volume pot wiring.

The pot looks wired OK, but do you know why it has four terminals?

I found the problem, My mini stereo input jack was jacked up.

Its all working now!!

Sounds amazing LOL :-)

I have this system on a JBL EON 305 with a 10ah Battery pack and it cranks.

This is a legit portable waterproof battery powered PA system.
