What is the best amp to power my 2 Rockford Fosgate HX2 RFD2212 PUNCH subs

these are supposedly the specs on em...
# Impedance 4 ohms
# Cone Material Fiber Material!
# Surround Material Santo Rubber
# Sealed Box Volume 0.8 - 4
# Ported Box Volume 1.75 - 4
# Port diameter 4"
# Port length (inches) 10.75"
# Dual Voice Coils
# Sensitivity 88dB
# Frequency Response 26 - 0.2k Hz
# RMS Power Range 150-500 watts!
# Peak Power Handling 1000 watts!
# Top Mount Depth 5 13/16
# Cutout Diameter or Length 10 15/16
# Vas 75
# Fs 29
# Qts 0.48

They will be in a sealed box in the back of a 91 camaro, Not too sure on what amp to power them with, thanks in advance :-)

this one would do great with them.

Rockford Fosgate 1001bd would be much better. 1000 watt rms, stable at 2 ohms. the subs are 4 ohm SVC so you cant bridge the amp to those subs to present a 4 ohm load, you would just run each sub to its own channel. 1001bd is a mono class D amp so it produces much less heat than the other amp, and is more efficient, so it wont draw as much current.

Hi, I'm totally new to this forums, I live in Australia, I'd like to know what type of amp would i need to use with a Panasonic CQ-HX2083U headunit, pioneer TD-690R 2-way 6x9s 330w speakers, pioneer TS-C160R 6.5" component speakers, a sub will be added later on.. the headunit produces 60Wx4, the rms for the 6x9s is 80W, the 6.5" is 60W, i'd like get an amp to run everything, ie the speakers and a sub,is that possible?? Also to chose a amp to power the 6x9s and splits do i have to look at the rms output of the amp to match it to the speaker rms output...? anyhelp would be greatly appreciated thankyou
