Hey everyone, just finished installing 2 new knee speakers in the jeep. I disconnected both terminal leads on the main battery and then disconnected the secondary negative lead from the wire terminal as instructed in the speaker installation instructions from Crutchfield. (passenger side had to deal with the airbag and they wanted to be cautious) After working on this an hour or two in the evenings, I attempted to reinstall the battery leads (4 days later) and when i touch the secondary negative lead to the main battery terminal, it is wildly sparking. I've checked, double checked and rechecked again and i can't figure it out. I don't even have the main terminal leads hooked up to the main battery yet. HELP I have seen a couple of threads in other forums with this same problem but they never disclosed the solution. UGH

Still don't know WHY it happened but i just manned up and quickly threw it on the post and tightened it down. Everything works fine. Noticed the dome lights and dash lights coming on so that was prob the power draw.
