The electrical watt rating of the inverter is different than that audio watt output of the amplifier. Your best bet would be to go to the Rockford Fosgate website and look at the electrical requirements for the amp.
Even though the amplifier is rated at 1200 watts, it will consume more. The manufacturer will probably give the power consumption in amps, or at least the size of fuse to use in the power supplied to the amplifier. Use the following equation to calculate the power required for the amplifier. P (watts) = I (amps) x V (volts). For instance if the manufacturer says use a 120 amp fuse and you are using 12 volts in a car, it would be P = (120) x (12). P = 1440 watts. You would need a power converter that can supply at least 1500 watts continuously to feed enough power. You can always use a bigger converter because the amplifier will only draw what it needs. There is also one more issue, if you are converting from 120 V from the house, to 12 V for a car amplifier, you need to make sure that you are plugged into an outlet that can handle the load. If you are supplying 1500 watts on the 12 V side and you plug it into the house 120 V the voltage is approximately 10 times more. This means that the amperage will be 10 times less. so 120 amps at 12 volts = 12 amps at house voltage, so any normal outlet should handle it; however, if you find a larger converter like 2500 watts, the current would be I = P/V: I = (2500W)/(120V) I = 20.8 amps. Most house outlets can handle 15 to 20 amps. You run the risk of popping a breaker.
For optimal performance, match the amplifier's power output to the rating of your subwoofer. The Rockford Fosgate 12" starts at a 150-Watt rating.
A Rockford 250 watt amp would compliment a 12" Subwoofer very nicely.

rockford fosgate beats jl power wise and prices. jl audio is also a excellent brand but in terms of power vs performance jl audio has an edge. jl audio is alot cleaner bass than its counter part rockford fosgate. jl audio provides its lows as well as high clean bass with good power. their over priced for quality though. rockford fosgate will out perform with deep louder bass. both cea rated for true wtts. rockford fosgate is excellent in prices beating jl audio from as much as 50$ - 100$ in getting virtually same high quality. rockford fosgate is better in their new 2011 models which are cleaner and underated for their power output.
75 x 1 Watts RMS @ 4 Ohms 150 x 1 Watts RMS @ 2 Ohms
How much power can the subs take in terms of RMS wattage? You can either wire them to a 4 ohm load where they will each see 125 watts, or to a 1 ohm load where they each get 250 watts. Rockford Fosgate supplies a very useful feature for showing how to wire the subs for the impedance that you want: http://www.rockfordfosgate.com/rftech/woofer_wizard.asp
you might have you subs hooked up wrong i the box idk check and make sure might blow um
I got the rockford T1D212, am using a 2000W RMS, Sedona Series Class D Mono block Amplifier by precision. it's a great amp.

Question: Can a power amplifier amplify the power? An amplifier can amplify the voltage or the current. Power can be converted to heat.
A voltage amplifier does not have to supply significant current bur a power amplifier does.
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
