How to wire my DVC sub to my Rockford 401s amp

Question

I'm have a little problem coming up with the best way to wire my system. I have one Crossfire DB3 sub that has a 4 Ohm duel voice coil. the sub is rated at 350 watts RMS continuous usage. My amp is a 2 channel rockford 401s that is rated at 100 watts RMS x 2 at 4 ohms, 200 watts RMS x 2 at 2 ohms and 400 watts RMS x 1 at 4 ohms bridged.

Answer 1

Wire each voice coil in stereo.  RF 2 channel amps are 2 ohm stable in stereo and 4 ohm stable in bridged mono.   With that amp and a single DVC sub, a dual 2 ohm is the way to go.  

Answer 2

Tough one, here's a couple options though: http://www.the12volt.com/caraudio/woofer...

it really depends on what you wanna do, you could underpower it by about 150 watts or overpower by 50, ur choice on that one...
