Basically what the title says, a friend of mine just got a sub and he doesnt have the amp or box to install it yet but we want to make sure it works before he pays for it. So how do you test a sub free air without damaging anything? Its a 1500rms sub if that helps?

just hook it up to any amp that can handle the subs voice coils and play it at low volume.

Arent you supposed to use like half or one third of the rated rms power or something like that?

You're pretty much fine unless you really crank it

you'll be fine as long as you don't turn up the volume, or you could just get a 9volt battery and hook up the + and - to the sub if the sub is good it should move.
