for starters it might help to know what power ratings the subs have

how many watts RMS per sub
how many watts Peak per sub
how many ohms
are they Dual Voice Coil or Single Voice Coil

something with a power range of 1000watts rms at 1 ohm would satisfy your need.

NEW ALPINE MRD-M1005 1000w MONO CAR AUDIO AMPLIFIER AMP - (eBay item 180190000594 end time Dec-15-07 22:05:26 PST)

i have experience with this one. my friend hit 145 or 146 db on termlab. almost as good as my 148 on my 15's. and they set off alarms from a good distance. around buildings and such.

even the Alpine MRP-M850 would work just fine for those subs, cause i have the 12" Kickers with the same power rating as your RF Punches...so either of these 2 amps would work just fine.

but I'd go w/ 2ohm subs with a monochannel class d amp...the bass will be cleaner, and it will hit harder. the lower the ohms the less impedance, which means lower resistance = better sound.

make sure you get a sub enclosure with the proper air space.

that amp would be fine too... but because of the specs he has shown. he'll need an amp that will work at 1 ohm.

(dvc 4ohm)
