There could be any number of things wrong with your amp. Normally there are diodes that protect against this sort if thing however applying reverse polarity on capacitors, regulators and FETs can cause untold damage. You will need to trouble shoot the amp by measuring voltages around the power supply.
if all your fuses are blowing, you are crossing over or arching somewhere. Check you wires connecting to the amp and make sure everything is tight and that no loose strands are touching other wires around it. Hopefully the amp isn't just coroding out under the outer shell causing an internal short.

if the inline fuse is blowing, you are putting out more power than what is getting to it, thus overloading the fuse and blowing it. Try a bigger fuse first and if that doesn't work, you will need to get a larger guage power cable with the bigger fuse. Also check your ground is properly grounded.

well really u can take the remote wire from the amp to a kill switch mount it on the dash and then the kill swicth to the fuse box. put it on the fuse that says radio hook the remote wire up to that and remember that when u wrap the wire around the fuse make sure that it stays in place . or u could have a bad ground its one of those though and u dont really have to run a swith or a kill swicth u just go srtight from the amp to the fusebox under the dash let me no if any if this info works.
The best I advice I could give you right now is to check all of your connections. Check your ground. make sure it is a solid connection to bare metal. I wouldn't recommend using an existing bolt on the car like a strut tower bolt. If you do clean the surface to bare metal then attach the ground. If you check all your connections, make sure nothing shorted then you might have a problem with the amp. What impedance are you running your subs at and what impedance is your amp capable of? My brother had 2 12" subs wired to 2 OHMs a piece wired together to make 1 OHM into a 2 OHM stable amp. This made his amp shut off and blow fuses. So, check impedances. I hope I could help. -Andrew Hawkins
make sure no of the speakers wires,inputs or antenna even cable is runnig parallel wite an electric cord or line.that is 90% reason 4 feedback(humming). Iif you have to cross wires do it in a intersecting way.perpendicully<if thats a word.rating please
as your sub is only rated to 400w rms simply connect the sub to either a or b channel outputs you may wish to use an rca splitter before the amp to feed both left and right audio channels into a single channel on the amp. WARNING connecting both channels on the amp to the sub will overload the sub and possibly blow it up so i highly recommend not doing so.
i was not able to locate a manual but i did find some interesting information that hopefully may help,
The AudioBahn AW1000X Car Subwoofer Features: dual 4-ohm voice coils, non-pressed pulp cone, huge foam surround, frequency response 23-500 Hz, power range 50-600 watts RMS (300 watts per coil), peak power handling 1,200 watts, sensitivity 91.1 dB, top-mount depth 5-1/4" ,sealed box volume: 0.4-.95 cubic feet, ported box volume: 1.632 cubic feet.
i'd need more info but from what you've stated, sorry to break it to you but it sounds likely you've incorrectly wired you speakers and blown your amp. this will prove no doubt an expensive mistake and learning exercise.
to drop the amp load to 1 ohm you need to divide the output signal path and the best way is by wiring a second woofer in parallel as seen in the ideal diagram attached this has the desired effect of doubling the volume .
since 2 ohm divided by 2 is 1 ohm load connected to your amp.
so the short answer is no you can't do that with a single woofer
Generally there are 2 parts to this problem
input signal as these woofers are just subs remember to give them a low line in signal before the amp (see diagram) i like to use rca low pass crossover filters from harrison labs (see link)
is the wiring configuration of the 2 woofers by wiring them in parallel as shown in the diagram you reduce them to a 2 ohm load for your 2 ohm amp meaning you'll get max loudness and efficiency
