how to TEST SPEAKER POLARITY in doors...

[bobo244 10+ year member]

I just recently replaced the speakers in the doors of my 96 silverado. However after thinking about i may have hooked up the positive and negative opposite on one of the speakers. Is there anyway to check the polarity by using a voltmeter or something, or do i have to take the doors off and unsreww the speakers and check??

just got a new DVM and wondering if it can help me here.

well, if you can see the cone on the speakers you can try using a AA battery. hook up the wires to the battery, +wire to +battery and -wire to -battery. If the cone moves out then they are wired correctly, if it moves in then switch the polarity and then it will be correct. just don't use too big of a battery or you will do some damage to your speakers. a AA battery will work though.

In order to use a DMM youd need to take the speaker out anyway so it doesnt really matter. That is if i understand your question correctly.

I would say if it just doesn't sound "right" as far as the bass, you may be alright.

can anyone answer this question. i hooked up my back speakers and it sounds fine but when i fade it to the bacj, and then to the back left speaker it cuts out the tweeter. any ideas on how to correct this? or should i just not be lazy and open my door and check the wiring? //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
