Okay... you have my attention. I am in the process of building a Street A CRX for the 2011 season and your subs (and this post) caught my eye. Its an '89 HF and I'll be using a Crossfire VR4000D (for starters)...so figure 3400-3600+ watts (conservative). Per Crossfires' Tech dept. the sweet spot is 1.4 ohms,so I am looking at 3- 2 ohm dvc subs. Based on your experience what do you suggest my best course of action would be in relation to box volume and tuning? (maybe 1 8" port or 2 6" ports) Thank you
