This amp is rated at 500 watts into a 4 ohm load bridged mono or 250 watts x 2 into 2 ohm load stereo. Do not go below that impedance in either case. The amp was meant to dissipate a certain amount of power, driving it to hard will lead to damage. Your speakers look like they are dual voice coils @ 4 ohms each. To get the max power while still saving your subs would be to parallel the voice coils on each woofer then run them in stereo with your amp. Stereo 2 ohm is 250 watts per speaker.
Safe down to 2 ohms, NOT a 1 ohm stable amp, it will be pushing it hard even at 2ohms but Fosgate's should be able to handle it providing that the install and all cables,wire,connections,etc. are sanitary!
Good Luck !
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up without the thermal LED being lit, the wiring needs to be checked. If it still indicates that it's in thermal protection, it needs to be serviced. A local repair shop will be the quickest. Rockford will email you the schematics.
It has two speaker terminals which allows you to wire muliple subs to the amp easier than trying to cram the wires all into one set of terminals. The two sets of terminals are wire in parallel internally on the amp, so it matters no which + or - you use on it. However, you need to remember they are already wired in parallel internally, so if you were to wire up two 2 ohm subs, the amp would see a 1 ohm load (which it's not stable at), not a 2 ohm.
dual voice coil subs hook up mono on amp, from amp - from right side + from left side of amp run to sub n then jumper wires from one side of sub to the other side goes negative jumps on positive and positive jumps on negative
There should be a live feed to the radio when the ignition is off.....this allows the radio to save stations! Check there is a constant live feed to your radio!
There is no chance that the thermal protection burned up and the unit still works. The thing you need to find out is why it did that. Check the speakers and the wires for shorts and proper impedence.
Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty . Send to Rockford Fosgate for repair

Time to invest in a volt meter. A test light can show voltage and not actually be a 12+ volts.. A capacitor will store energy for yoy but first verify correct voltage.

Are you referring to the terminal screws? Pull one of the others and go to local hardware store for replacement.
