So I tore a surround on my ARC Moto 062's, after repair I started noticing some threads on polarity since the 602's aren't marked. Doing the aa battery test mine are wide post positive, narrow post negative. Which brings me to my current dilemma. Amp is a BT2180 .Does anyone know what the Voltage DC should measure on the speaker wires coming out of the amp. Mine measure:
LF -.5
RF -2.0
LR -.5
RR -2.0
Yes all negative readings which means the polarities are reversed coming out of amp??? So in theory if these are reversed I am basically hooking up my speakers reversed???
Also why would the lefts measure less than the rights????

 

 

I guess i'm going about this wrong??? when
i measure the leads in AC I get 0 readings

 

 

So I followed the video, helped tremendously. As I increased volume my values went up and lost the "negative DC readings" Not that i was try to adjust input gains, I was just very confused why I was getting negative DC readings, forcing me to believe I was getting reversed polarity readings. I never thought a 12 volt system would take AC readings. The only explanation for "my theory" would be the BT Titan amp outputs were reversed which I suspect would have been highly unlikely. I like to test and experiment but my mistake here. Thank You In The Wind !!!!
