Ok I hooked up one of my friends subs for him about a month ago and I am wondering if I did it correctly. It was a rockford 12 " not sure of rms or stuff but it was 4 ohms resistance. I conected the positves and negatives to each other on the sub itself then ran the "spare line" to the amp where I had it bridged that is something for watts at 4 ohms. what kind of load would this be running on the amp? It is a 2 channel amp would it be better to run each voice coil on its own channel?
