Hell no, lol! That's waaaaaaay to much $ for those amps.
The Crossfires are great, but on that budget I would get a DD Z1. 5000+ watts at 1 ohm, excellent quality and efficiency, one of the best amps out there.
Crossfire VR4000D is way over 5000 watts rms at 1 ohm at 12.5 volts, not to mention even more at 14.5 volts. Just putting info out there. They are only like 800-1400 dollars depending on condition and where they are sold. Yes DD is the Sh!t but I would perfer the Crossfire. JMO
well im looking for a good sub like a DD3512d2 or better thats not 800+$'s but thanks for your advice Sinful systems. If u know anything better than DD3512d2 for SQL let me know tho.
So would be the Fi BL/BTL be a good sub to buy that will sound good with a small amp and when i want up upgrade i can just feed it more power with a better amp and electrical system?
