AMPS and Relays, Do They Affect Each Other?

I made a switchbox and installed some neons hooked up to it this weekend. I wired a relay so that I could grab current from the battery (via a distribution box) and make sure that they turn off when the ignition is off (I didn't want to overload an existing circuit in the car).

Now I have the relay next to the Amplifier and the distribution box, I notice that sometimes if I move the switchbox, the relay starts to click. Do I have a loose wire or is the Amp affecting the relay? I'm probably going to check the wire, but I want to know if such interference is possible.

is the amp on when it does this?
does it still do it when the amp is off?

if you have it close enough to the power supply then the magnetic field might trip the relay (if it's a magnetic relay that is), but I find it pretty doubtful. My guess is it's a loose wire

Yeah, I'm going to check the wires, it is a standard 40 amp relay though.
