I felt like an idiot when installing my girlfriends total mobile audio t250.1 the other day. I was ready to make my sub to amp connection when i saw two positives and two negs like this (+ + - -) I asked around and it appears its internally bridges to make wiring in parrallel a lot easier and less confusing, really cool idea i think but made me feel like an idiot.
