Hifonics BXI 1210D
or
Kicker zx750.1
Both wired at 2ohm produce around the RMS of your subs.
Kicker cvr 12 = 400RMS
400 rms X 2 = 800rms
both cheap amps!
kicker zx 750.1= 750 rms @ 2ohm
hifonics bxi 1210D= 900 rms @ 2ohm
OR a
Boston acoustics GTA 800 amplifier
little pricy.. might be able to find one cheap if you do some searching,,
800rms @ 2ohm it produces..
hope it helps!
