Hey guys, so I want to be able to easily adjust the volume on my subs when I get them installed. So I had an idea the to use a bass/gain knob. Now I do not want to use this to ever turn my subs up over what they are tuned and set to. I just want to use this to turn down the volume of them for instances like driving into a parking lot so that I'm a little more inconspicuous about having subs to prevent theft, or driving through neighborhoods, or when roll past a cop haha. So how would I go about doing this? Would a bass/gain knob be the right way to go anyways? And if so when I install it would I install the knob set to max so that the only way it can adjust is to go down? Hope this isn't a dumb question or confusing.
