Look, you have purchased some absolutely high end subwoofers. Why not get an amp that lives up to that standard? Your system as a whole is only as strong as the weakest link in it. Right now, i'd say that would be your amps. I know it can cost a lot of money to get some mean *** amps to go with those beast woofers but it's really the only way to do them justice. I'd recommend looking into some US Amps. They are my personal fav. They don't play games with power ratings, what they say the amp can create is usually a little under what it does. I'm about to put 1 RE SX/MX 18" in the back of my rodeo with 1 us amps AX 1500 DE on each coil. I'll post the pics when it's installed.
