Which setup would you choose?

Im looking to change subwoofers in my car stereo. Right now i have a single 12' but im thinking of changing to either one 10' or two 10's. My options that im looking at right now are two of these, http://www.bestbuy.com/site/Polk+Audio+-+10%22+Dual-Voice-Coil+8-Ohm+Subwoofer+-+Black/1001334.p?id=1218207315071&skuId=1001334&st=polk sub&cp=1&lp=3 or one of these, http://www.amazon.com/Rockford-Fosgate-P3D410-400-Watt-Subwoofer/dp/B001AQTZKY. I have an amp that would power both of these at full easily, with an aftermarket headunit and speakers/ 4 channel amp if that helps. If you have any other idea's under the 200$ range for 10' please throw it out there
