I got 2 12 inch HE2s in a sealed box (mine is Masters of Bass not RF, but it feel spretty solid) and they are running off the 700s and sound pretty good. When the gain is cranked all the way up things sound kinda crappy but I never really need it that loud and I don't think most amps run good at full gain anyways. I think if the HE2 wound good with the 700s then those should sound good with that or less (I think those are single voice coil right?)

Thanks sparq, i was a little worried about a 1000 watts...LOL

i'm not sure if i understand this....

"Woofers: This enclosure is loaded with two 8 ohm Rockford Fosgate Punch HE RFP3812 12" woofers and has a separate terminal cup for each woofer. When the terminal cups are wired in a stereo configuration, each channel of the connected amplifier will see an 8 ohm load. When the terminal cups are wired together in a parallel configuration and connected to a bridged amplifier, the amplifier will see a 4 ohm load. The power specs in the Crutchfield database are for 4-ohm mono operation. When wired in the 8-ohm stereo configuration, power handling is 200 watts RMS/400 watts peak per woofer."

Does this mean i'm gonna have to pull the woofers to wire them for a 4 ohm load...???:bloated:

sorry i'm not good at this stuff....lol

correct!! take the subs out and wire them in parallel which should present a 4ohm load. now you would only have to use one terminal cup. connect the bridge amp to the terminal cup(one that you are using to supply the power) and this will give you 380watts RMS at 12.9volts. at 14.4 volts, it will make ~420watts, giving each sub ~210watts. watch out for the gain also. rockford fosgate amps are underrated, so you might not know what you're getting :)

if you need a wiring diagram, let me know and i'll post one right here.
