I'm new to this site but it looks extremely helpful. I'm about to purchase two of these 12" subs and was just wondering how much rms power you think they can take from a monoblock amp because i was thinking about gettin a crunch 1000 watt mono amp to run both off of since they say 600 rms each and then maybe adding another one when i get some more cash. What are you comments or suggestions on these subs i'm looking at or the amp. I'm also going to probably get the box at this site http://www.xtrememobilesolutions.com/kvported12dual.html for the subs so if you have any comments on that it'd be greatly appreciated.
