my amp might have pushed the sub out of phase!

Posted by thump on January 18, 2017 at 02:32:13:

i just bought a multimeter tonight to test my battery voltage and found something REALLY strange when i decided to test what wattage i'm listening to right now on a pair of JBL northridge outdoor 2 ways i got a deal on.

the left channel consistently measured -.09v @20v setting and -.22a @10a or -3.98w if i did the math correctly and +.03v to +.04v and +.09a on the right or .72w.

the left channel is out of phase, so i might have been bridging L+ to R+ instead of L- to R+, and the woofer may have been firing out of phase and bottoming out.

does that make sense?
