I'm a big fan of the W6V2 (though I would NEVER pay retail for them), however, they're built as more of an SQ sub. They sound great, but if your primary concern is to get loud, there are much better options out there. The 1500 watt amp may be a little overkill. The 13W6V2 has an optimum power rating of 500 watts and warranty void past 750.
Yes if your looking for something with output like an L7 I wudnt be looking into w6v2 not saying they can't get loud but w6v2's are more sq/sql subs... I think you r looking for a more SQL/spl sub try looking into RE SE alpine type r or x.... the T1s will get Loud and sound ok doing it tho... I like the looks of t1's btw inverted ftw lol...
I'm actually looking into what will hurt my ears the most. a 12 W7 really feels like something is pounding in my ears. It will be in the SUV of course. I don't really want Type R, but Kickers I've heard break easily and they are actually sort of expensive. T1's I've never heard.
