rockford fosgete system
would 1 rockford fosgate 501s amp power 1 hx2 12" sub, the amps specs are,125 watts RMS x 2 at 4 ohms
250 watts RMS x 2 at 2 ohms 500 watts RMS x 1 at 4 ohms in bridged mode stereo or bridged mono output 4-ohm stable in bridged mode Tri-Way capable requires 8-gauge power and ground leads and a 50-amp fuse — wiring and hardware not included with amplifier continuously variable 50-250 Hz high-pass/low-pass (12 dB/octave) crossovers MOSFET power supply and output devices MEHSA mounting technology increases the heat transfer from the MOSFET output devices to the heat sink, for higher power output, lower operating temperatures, and greater reliability TOPAZ — noise-killing differential inputs that eliminate 80% of ground loop noise Trans•ana circuitry keeps preamp voltages low and signal paths simple for outstanding audio quality NOMAD — advanced protection circuitry for "intelligent" shutdown protection wired remote included for fingertip control of Punch Bass (0-18 dB boost at 45 Hz) speaker- and preamp-level inputs 12-1/16"W x 2-3/8"H x 9-7/8"D AND THE SUBS SPECS ARE: Sensitivity: 88 dB RMS Power Range : 500 Watts Peak Power Handling: 1000 Watts Impedance: 4 Ohm Low Frequency response: 26 Hz High Frequency Response: 200 Hz Diameter: 12 Inch Features Dual 4-ohm voice coils CONsealer gasket hides mounting screws and prevents air leaks around the frame Frequency response 26-200 Hz Power range 150-500 watts RMS (250 watts per voice coil) Peak power 1,000 watts Sensitivity 88 dB SPL Top mount depth 5-13/16" Sealed box volume 0.8-4.0 cubic feet Ported box volume 1.75-4.0 cubic feet

Re: rockford fosgete system
Or build your own box
I built mine in 2 days between classes in the engineering shop on campus, it's definately not hard if you have the specs of what you want to build.

Re: rockford fosgete system
but will this amp power the sub as good as possible, the 4 ohms and 2 ohms aren't matching up i think, please look over the specs and let me know if the amp will power the sub at either 2 or 4 ohms

Re: rockford fosgete system
no, you will be sending 250 watts to that sub.
Find something that puts out the power you need into a single 2ohm load.
