REFF'SMy linkEBAYhttp://feedback.ebay...ck&myworld=trueI love car audio so much because I will never be done. I can never win, and I will never get it finished or perfect. It always has me coming back for more, I can never get my fill of it, but I get what I need. Link to comment Share on other sites More sharing options...
snafu Posted September 9, 2015 Report Share Posted September 9, 2015 No. What I'm saying is that you can't determine this with a DMM. The answers are out there guys. If you're a car audio enthusiast and don't have straight As in math, science, and Phyisics, you're doing yourself a dis-service.

sundownaudio Posted October 4, 2015 Author Report Share Posted October 4, 2015 Use a dmm and measure the resistance between that point and the front battery. My guess is it's high which is no good. If however the resistance is real low you are fine. i used the multimeter and got a reading of 0.02/0.01 on the 20k setting does that mean the ground points are good ?
