Welp finally found yall since my last computer crashed :D I need some help picking a new setup for my subwoofers, I been searching again for something that can kick me harder then what I have now. Which is 2 daul 2 ohm kicker CVR's with a Alpine v-power 1,000 watt amp and to be honest it barely shakes my mirrors...but I think its the crappy free ported box I have them in. I need opinions from the stuff I've been looking at, I want a system that can make my heart skip a beat, make my truck feel like its falling apart, makes my house feel like an earthquakes about to hit. Well you get my point here mainly looking for shake then sq, heres what Ive looked at: 1. 2 12" or 2 15" Alpine Type R powered by an Alpine PDX-M12 2. 2 12" or 2 15" Memphis (no idea what series) no idea of an amp either yet 3. 2 12" 512b or 2 15" 515b Digital Designs no idea of an amp trying to stay under $300 a piece for subs thanks to anyone who puts in input and their own opinion on other subs that could out class these for the price but pick one of the three atleast.
