This isn't my first post on this subject, so be patient with me. I am looking at Cerwin Vega subs right now because I've heard them before and was impressed. I am rather confused between each of their model lines - the VEGA (now discontinued), the V MAX, the Stroker and the HED. I've looked and looked for information, but thus far have not found definate answers. I do know that the Stroker is their competition series and that it's too powerful/big for my uses.
I'm looking to add one or two 8 or 10" sub(s). Do you think I am looking at the wrong brand? Would you recommend opting for the DVC over the SVC? Also, does anyone know of a good resource to explain ohms and calculating resistance? I've tried to comprehend it, but something is lacking in my understanding of it. Thanks for all your help!

P.S. - I'm going to use ported boxes in my Civic.
