are these P1s or P2s? in the picture they look like p1s but in the discripton it says p2s.. but either way, your going to want to spend more then 100 dollars if you want those subs to perform nice. If they are P1s then go with a Rockford Fosgate R500-1 amp (since you dont want to spend a lot of money) and if they are P2s go with a Rockford R750-1d amp. If those are too expensive then try to find an amp that puts out 500 watts (if they are P1s) or 800 watts (if they are P2s).
