I have used both, so I'll pitch in my opinion too.13w3v3 is rated for 400 RMS (read the manual it comes with when you buy 1) The most it can handle is 600 cont. Frankly, I wouldn't push any more then 600 on it. I also think the w3v3 line up is garbage, the older w3v2 was a much better SQ driver. For Sound Quality, I'd take a 15w3v2 over the 13w3v3 anyday. As far as the kicker l7 12" goes, it can take about 1 kw daily, and will get much louder as a 13w3v3. SQ between them will be about the same, because like I said previously, I think the w3v3 was not an "upgrade" for the w3 driver series.
