Pioneer car speakers

[evident]

I have a pair of pioneer TSA-6981's in my car, but I cant tell which connection is posi or neg. I don't want to hook them up to my sys and cause damage to them if they are reversed, and i don't have anything i can hook up to it to do the pop trick.

anyone have these and can tell me which end is pos. and which end is neg?

UPDATE:

Ok, upon closer inspection there are two stubs, one is twice the size of the other, i believe that side is positive. hooked them up and they sound right.

here's what happened, I had a basketball in the trunk and it was rolling around, musta pulled the two speaker wires off of the speakers... I need to secure the wires to the top of the trunk prob. Thanks to all you who replied =)

PS. Pioneer makes a sweet car setup! I've had these for a year and they rock. Don't even need a sub in the back. I spent about 450 total ( front, rear, head unit, amp) on it and no complaints at all

Is it possible to use Multimeter to determine it?

Wiring speakers out of phase will not damage the speakers, only the sound. As long as the 2 speakers are wired the same as each other, they will be in phase with each other, but may be out of phase with the other speakers in the car. You can use a battery (1.5V is best but 9 is OK) to see which orientation of the wires causes to cone to move outward when the battery is connected to the terminals (assuming you can see the cones of the existing speakers).

He said it. Use an AAA/AA/C/D battery if you have one. (9v may be pushing it a bit.)

Attach wires to the speaker terminals. Touch wires to the battery's +/- posts. If the speaker moves OUT towards you, then the battery's + terminal is attached to the speakers' + terminal. If the cone moves IN, then the leads are reversed. Easy.

turn it upside down, usually the negative is on the left, positive on the right
