keep the subs or not?

well i have 2 cadence 12" 4 ohm subs that i have had for about a year now. they have NEVER been used because ive been looking for a good amp to run them i have now bought a car that the subs are WAY to big for (a firefly) and am wondering if i should keep the subs and get 2 smaller boxes and continue to shop for an amp or just sell the subs with box and spend money on some other subs (i so wished i bought the 2 ohm ones instead):banghead: :banghead:

i only would need at most a 10" sub for this car as im not even running more then 5" speakers right now and its loud.
ive got a friend willing to pay $200 CND for them which is about what i paid for them new.

so is there even an amp out there that can power these subs for a reasonable price? (needs 300W RMS per sub at 4ohms)

heres some ideas. you can get 2 of these. http://www.eclipse-web.com/amp/xa1000.html
