Currently running a Exodus Shiva X2 SVC 4ohm in a 1.5cuft sealed box. Its an awesome subwoofer BUT, I was wanting to add another one but since they are no longer available thats not possible. So i'm looking to upgrade for more output and perhaps deeper extension. This brings me to the SD X series. Anyone have any opinions on whether the X 15 would be a worthwhile upgrade? My amp right now is a Soundstream PCX 1500D, specs claim 800watts 4ohm, 1100watts 2ohm and 1500watts 1ohm. I would get the X 15 D2 so I can wire it to 1ohm and would like to go sealed. No crazy about ported in the car. Fronts are Hertz HSK 165 XL so midbass and output are no problem. I know this is the Sundown forum but some other subs on the shortlist is a pair of TC Sounds Epic 12s, LMS -R 15 and perhaps Dayton Audio 18" HO or pair of 15 HOs.
