i dont know i just bought it today i wont have it until this weekend. the crossfire worked great until it popped a capacitor for some reason, probably from me running it hard with only one battery and the voltage dropping hard.
from everything i've read the vfl's are freakin bulletproof, drop to ridiculously loud resistance loads and take 18 volts stock. does well over 3kw. i purchased it from btnhfan, he has another one for sale, check the classifieds.
are you talking t2's or p2s?
