huh?do-what? Posted May 18, 2011 Report Share Posted May 18, 2011 isn't clipping DC voltage? If your amp is putting out dc voltage you might have bigger problems than clipping i didn't mean nothing but straight dc voltage. I always thought that when the ac waveform flattens out, that represented small amount of dc voltage. googlesearched and apparently I was misinformed. God damn its hot today. My balls are stuck to my leg. Link to comment Share on other sites More sharing options...
stefanhinote Posted May 18, 2011 Report Share Posted May 18, 2011 Your speaker wires going to your speakers carry AC (alternating current) electricity, there is phase, not polarity. The electricity is alternating from positive to negative, thus causing the voice coil to move inward and outward. So I believe your theory about using a dmm to check for clipping does not work.

mken4392 Posted May 19, 2011 Author Report Share Posted May 19, 2011 It was pouring rain here today so I couldn't test it out on my truck but my home system does not go negative on the meter. Hopefully its nice so I can check again tomorrow. I just figured I'd throw it out there to you guys and see theoretically what was happening.

MrSkippyJ Posted May 19, 2011 Report Share Posted May 19, 2011 My guess is this. It really depends on the refresh rate of either your dmm or the dmm display but I am guessing you dmm only shows a single polarity your are clipping pretty badly. If you clip a signal bad enough you are effectively sending a DC signal to your speakers.

HHR Ed Posted May 19, 2011 Report Share Posted May 19, 2011 what setting was your DMM on? AC voltage changes phase from + to -, thats why its AC. So it really shouldnt work that way.
