Any couple of 600W RMS subs with an EBP of 70 or less that fit your budget would easily work. For example DC audio level 2 10, Obsidian audio 10s, Alpine Type Rs 10s, RE Audio SEX 10. Many more I'm sure.
you should try boss audio they are cheap and very good i have one 12 in 2300 watt max and 1150 watt RMS on a boss riot R1100 mono block amp and it gives all the bass you will ever need
