mbdblue Posted June 1, 2008 Report Posted June 1, 2008 Just wanted to share this with everyone. I mentioned a couple months ago that I learned if an amp doesnt see a good ground connection, theres a possibility that it will try and "steal" it from the RCA connection. I just experienced this myself puttin in the E8s. Makin a vid, I go to turn up the volume and all the sudden nothing. I check the amp....protect. Now I go into auto-pissed. I need to find an answer.....Im sure we've all been there. so heres exactly what I did. pulled DMM out of somewhere.....(somehow I knew where it was....believe me I wouldnt have known if it was any other time) checked voltage at amp- saw 3.3 (LAME!) checked front fuse-fine checked amp fuse- fine checked bat voltage- fine unscrewed subs- still protect pulled 1st pair RCAs- protect pulled 2nd RCAs- amp powers down check voltage at amp- 1.4 WHAT???!!! check ground location with power wire (car running)- BAD! checked past ground screw with power wire (car running)- 14.3!!!!! changed ground location, re-hook RCAs, good to go.

Guest Posted June 1, 2008 Report Posted June 1, 2008 in some cases, some RCA's are grounded to the HU, so pulling them might make the amp shut off if the real ground is bad. try changing up your grounding point and/or wire to see if its bad
