I am thinking about pulling the trigger on the following:

M80s, VP150 iw/ow center and the EP125 sub. Having read some threads I shouldn't I be concerned with my current Denon 2809CI amp to push these, right?

My main questions is my homebuilder pre-installed some thin gauged speaker wire (maybe 20 gauge) would this smaller wire put up too much resistance? Should I replace this with something with less resistance like 18-gauge?

Thanks,

Kevin
