After Prewire, how to test speaker circuits prior to hook up? (1 Viewer)

[todbnla]

I have run all of my 7.1 wires and was wondering if their was an easy way to test the wires prior to hooking up to the main output? In other words, can I use a device like an ohm meter to test for shorts or breaks in the line?

Yes. You can test for shorts by setting the meter for continuity and connecting the meter leads to the speaker cable’s (+) and (-) ends. There should be no tone. (If the speaker cable is multi-conductor, cross-check all conductors the same way.) If you do get a tone indicating a short, the first place to check is the other end of the cable. It’s possible that when it was cut, some loose strands may have shorted together.

To check for breaks, connect the meter leads to the speaker cable ends as before, and at the other end of the cable tie the ends together. You should get a tone.

Hope that makes sense.
