[QUOTE="Papermaker85, post: 8314895, member: 572595"] Bad connections mean higher resistance. Depending on the situation it can lower effiency. If its st the amp your going to get a lack of output. If its at the alt your going to get lack of output. Usually a bad amp ground won't cause major voltage drop cuz the resistance is high so it naturally don't pull as much current. Where as the alternators ground will limit the alternators output causing the voltage drop. Make sure u have the alt battery and amp ground to the frame. Not the body. Chances are they might be isolated causing problems. [/QUOTE]
