Im going to be running 6 in about 10 cubes on 2500-3000 watts depending. Options are polk MOMO, soundstream pw-12s(http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=18134), RE re12, or kicker CVR 12. Im leaning towards the soundstream subs but i can get the POLKS for cheap. How do they all stack up? Also any estimates on how this is going to compare to my last setup(2 18" Fi Q's ported to 35hz on 2500rms)?
