Question... I have a sub box for 2 twelves that I want to run series/parallel. My box has a divider in between the 2 speakers. I thought about drilling a hole to get to the other side just big enough for the wire so it would be a better seal. My question is, would that be a good idea or should I attach the wire to the positive, then the terminal on the box on both sides and then join the positive wires on the outside of the box then run it to the amp? Or should I drill the small hole?
