From what I read about them they seem to be pretty good subs. All the reviews I seen were from like '99 - '00. Also, are they single VC or dual VC? I didn't look that far into them.
there dvc. i hooked them up and tuned em...on a hifonics brutus 1210d at a 1 ohm load which is 1200 rms. i heard mixed reviews on my amp. some say its overrated and only puts out around 80% of its specified power and in other places heard it puts out wat its rated at. its hitting pretty good now. i plan on getting a better amp in the future but for now im satisfied
