I need some advice please. I just bought a 2012 VW Passat with plenty of space in the trunk and I have plans to upgrade the electrical. I have never had any subs in a ported box (and plan to build a ported box, 4.5 - 5 cubic feet, for this system), have never had subs bigger than 12"s and have never heard SSA subs. I have a DC 5.0K amp that I would like to run at 2 ohms, so I was thinking I could go with either 2 ICON 12" dual 2's or one ZCON 15" dual 1. I mostly listen to rock and metal music, but do enjoy some dub step and bass drops, so I would like to be loud but sound great doing it. What would you go with? Also the ported box will be facing foward sealed off from the trunk and tuned to around 35 hrz.
