flwatersaver Posted December 27, 2011 Report Posted December 27, 2011 (edited) Both done with -0db tracks, full volume on head unit. Off of the RCA cables right before amps. I am looking for a portable scope. I am told the range for being off is +/-0.1 20hz and +/-0.5 at 10khz Edit I found a fluke 863 graphical multimeter Edited December 27, 2011 by flwatersaver Quote My selling FeedbackBuild log - Blazer C pillar wall, Two DC Audio 3.5k'sTEAM PSI

TonyD'Amore Posted December 27, 2011 Report Posted December 27, 2011 So when you have it connected at amplifier you get signal and distortion LEDs, but no 1kHz or 40Hz LEDs? Quote
TonyD'Amore Posted December 27, 2011 Report Posted December 27, 2011 when I run mine thru my external cross over I get the same thing ....... my external cross over is a Coustic XM-1.... I dont get it Sounds like your crossover is distorting the signal Quote

I have looked at them on a scope and they don't look that bad to the naked eye, but they are very distorted. I wouldn't want a headunit in my system that has this problem. Yes 9.5% THD!!

flwatersaver Posted December 27, 2011 Report Posted December 27, 2011 I tested it with the amp, Please forgive me as I am very tired, I have been on nights for 5 days now and only 4 hrs of sleep per day. http://www.youtube.com/watch?v=Pmf_38VY8ls I am going to go check my brother's pioneer headunit, to see what it does.
