Test Speaker 9v Battery

Test Speaker Wires with a Battery. Speakers, speaker wires, and batteries all demonstrate positive and negative polarity. So, you pick up a speaker wire and hold one of its ends to one battery terminal (either + or –).
Step 1 How to Test Speakers and Wires. Speaker Testing Option 1: Connect a 9 Volt battery to the leads of the speaker, positive lead to positive battery end and negative lead to negative battery end. If a pulse is generated in the speaker then the speaker is still functioning properly.
Is this OK to do to test the polarity/phase of the speaker system? A very knowledgeable friend of mine has said that I need to test my JBL tops .
I saw a thread where someone said you can test if the wiring to the speakers is ok by touching the speaker wires to the pos. and neg. leads of a 9v battery.
All you have to do is take a 9 volt battery and touch it to the wires.. I do use the AA test method frequently when trying to locate which speaker is tied to which .
It's important to have the correct speaker wire polarity in order to obtain the best. You will want a fully-charged nine-volt battery for this test, so just use a new .
My figures say that if the resistance of the speaker (nominally 8 ohm impedence) is 6 ohms, the 9v battery might pass 1.5 amps, 13.5 watts – too .
