    Speaker Polarity Check With A Household Battery

    This isn't really new in the realm of DIY'ing speakers. But still, it's something people ask when they are new to the hobby. So I figured making a short video explaining how to use a battery to check polarity might be useful now and again. It would've helped me when I first started.

    I just did this yesterday when I was hooking up my MIL's home theatre and didn't want to trace wires. Works so well.

    And the best way to tell if your 9V battery is good is to put the terminals to your tongue!!!

    If you want to impress me, do that with the AA battery.
