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.
1000w
The Rockford Fosgate Punch 100zx2 amplifier is rated at 100 watts RMS per channel into 2 ohms.
The Rockford Fosgate R150-2 2-channel amp puts out 50 watts RMS per channel to your speaker system, or you can bridge it to supply 150 watts RMS to a subwoofer.
400 i believe cuz i have two of em n my car
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
In my opinion the Rockford fosgate T2 subs are the best. They are pricey but well worth it. I have a t2 15" powered by a Rockford fosgate t2001bd (2000 watts) and it is the best system I've had.
They arent to bad...but it also depends on how much watts your lookin at? i would recommend lookin at some different amps before buying a MA audio one....i hear Hifonics and some rockford fosgate amps are good as well :)
A possible choice is a pair of Rockford Fosgate HX2's all parallel in a sealed 1.25 cf/sub box. That's about 900w per sub peak, probably 4-500 watts rms, which should be in the subs sweet spot.
rated at 22.5 watts per channel in stereo and under a 4 ohm load per channel.... although the birth sheets they were shipped with normally stated the wattage as tested to be around 75 to 86 watts per channel in stereo running on a 14.4 volt system... bridged possiby as much as 150 to 200 on 14.4 volts !! very stout little amps and ive seen two run 8 rockford 15's back in the day !! WOW !!
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.
the unit which are measured for power of lights are watts....
