Okay, I am looking at adding some thump to my system and I am trying to determine what subs and amp I will need. Lets say I am going to install 2 subs with ratings of 300W RMS, 600W max and 4 ohm resistance. What is the formula to determine the power (RMS) that the amp will have to supply? Would I be looking for an amp which is 300W RMS @ 2ohms? How would I wire this, 1 sub per channel on a 2 channel amp and if I wired this like this, would I be interested in RMS values at 4 ohms since that is all the channel sees? If I was to bridge the amp and wire this in series (one big loop) what values of RMS should I look for? Thanks for your help
