np, its kinda hard for me to explain srry, i dont know too much on this stuff
. but i go dvc's because i pump a lot of watts thru my subs (not in celica though lol ). my rockford dvc's(12's) can handle 1000 rms , 2000 peak watts a sub. i also like to wire the dvc's two ohm stereo (must have an amp that is two ohm stable). dvc's just allow you to wire them two diff ways. a lot of peeps go for bridged though, just personal preference.in the amp you were talking about, four ohm stereo only produces 90 watts a channel, where as under two ohm stereo it produces 180 watts a channel. i didnt click on the links because i'm about to go see a movie, but that amp most likely bridges down to 360 watts.
maybe someone else can help us who knows the specifics
