Can anyone please tell me which color speakerwires are positive and which colorsare negative?

My car is an '06 GTwith the shaker 500 and Ihave changed the 5X7back speakers and Iam about to do the5X7s inthe doors but I cut off the factory connectors and now Ican't tell which wire is thepositive wire. [8D]

Does it really make a difference if the speaker polarity is reversed? My speakers are JL Audio TR570and there is a tiny "crossover" on the positive connection ofeach one.

What happens if I getthe polaritywrong?

By the way, I am only concerned with the 5X7s as the crappy stock subs will stay for now.

Thanks in advance for any help.

Red is typically positive and black is negative.

It won't matter. I've tried switching the wires back and forth on speakers and can't tell a difference.

I wish it was that easy.....unfortunately,none of the wiresare red or black.

The polarity is important under load it can sound like ***, and its very bad for the speaker, unless your doing some special woofer ****.

This shows the colors at the back of the radio, but I dont know if they are the same at the speakers, ford is usually good for carrying the colors through but sometimes that change mid harness.

if that doesnt help you check the guys over at http://the12volt.com
they have some good info on audio stuff.

Have you tried hooking a multimeter up to the wires and turning the stereo on? That should give you an indication as to which is + and -. Another little trick is to hook a 9-volt battery up to the terminals of the speaker. When you have the positive terminal of the battery on the correct terminal of the speaker, the cone on the speaker should pop out. If it sinks in, you have it backwards.

your left front should be + OG/LG
- LB/WH
right front +WH/LG
- DG/OG

Try reversing the polarity of one speaker, and leaving the other one correct...then go listen and tell me there's no difference.

With a flat-coned driver that somehow has its madnet completely out of the way, you could theoretically reverse polarity, flip the speaker over 180*, and listen to it just fine. Unfortuneately, in real life, reversed polarity will drastically hurt clarity and output, in addition to virutally complete cancellation when played in unison with a speaker in correct polarity.

I did try that about 10+ years ago and couldn't tell the difference. They were just average 6x9's and tweets. I'll claim ignorance on the sound clarity, due to hearing loss and buying crappy speakers back in the day. I pay to have them installed now.

I found this out when I replaced mine.

The wire nearest the plug's clip is +. It's marked (very small) on the speaker half of the plug.

I got them both backwards at first.

Here is the thread. I got it backwards at first.
