im assuming your asking about how to wire 3 10's since you posted it in this section of the forum. i know many people that run 3 subs and its not difficult at all. it all depends on the VC config of the subs you want. tell us what subs you are looking at and if they are SVC 4 ohm, DVC 2 ohm, DVC 4 ohm, etc. then we will be able to help you out.
