I have heard that they are good amps, but far from the best. I would be willing to spend about 4-500 on each amplifier if I knew they would output huge power and last a long time.Burton made some good recommendations in the Audiopipe 3000's, solid amps for a smaller budget.
I would go that route and spend some money in a couple batteries for the back, quite a bit of decent 0/1g wire, doing the big 3 and even a HO altenator in the future with that kind of power.
Good luck!
