That's a 12v (output) wire from the empeg designed to trigger a relay - also known as "remote". Example: activating the motor for a power antenna and activating an amp's main power.

You most definitely shouldn't touch it to any bare metal on (or that's attached to) the car's chasis. That will create a short circuit (and I hope that wire is protected by a fuse). It's super-low current, so you can't really power anything directly off it.

So, if that's not hooked up, do you have another head unit triggering the JL amp and Bazooka? Or did they install some type of line-level trigger? I know the JL must be triggered by 12v connected to its remote input.
