How to test a sub?

[BradFrotic]

hey guys, I just found a 12 in Pioneer sub in the back of my buddies new car he bought. He let me have it, im not sure if it works and I was wondering if there was anyway to test it without an amp.
Can I just plug it into a stereo with some speaker wire?

Yeah, Ive hooked a sub into a stereo with a speaker wire. It doesnt sound good at all, but it worked. Whether its good for the sub/ stereo Im not sure, but it wasnt a permanent thing and as far as I know no damage was done.

So to just test it, give it a try.

just take a 9v battery and some wire and connect the battery to the sub... Should vibrate if it works...

really? I have some old computer speakers that I took out of the casing, I'll have to go try that!

it will just go in or out depending on the polarity

Just an FYI,

A 1.5 volt DC battery will do (E.G. AA, AAA, C, D, etc.) You don't need a 9 volt.

Just keep tapping the wires on the battery. You'll get a popping noise out of the speaker if it works.

I hate to yell when saying this so I'll limit it to bold font...

Do Not Hold The Wires On The Battery!!!

It can overheat the voice coil and cause the speaker to lock up. Tap, tap, tap is all you want to do.
