Rockford doesn't make an ideal amp for those. Did you already buy the subs? They are spendy subs. If has to be rockford, I would recommend 2 t1500's and the electrical to back it up.
Wouldn't get a Rockford amp unless there was a really good deal for their 2500, which wouldn't like being wired less than 1 ohm and wouldn't be at max power at 2 ohms nominal.
