Amp

http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=17651 im gonna get two of those  speakers and i needa kno what kinda amp i need

class D 500-800rms@ 2 ohms

I would not put over 300w rms to those subs.  If you got one better 12 and put the same power to it, better sound overall.

huh? the specs state 50-400rms tho..........

I have a great deal of experience with kenwood subs.  I would not put their stated wattage to them.  

lol....alrighty then......
