If you bridge the amp and get 1000 watts RMS and that is split going to two speakers then you will get 500 watts RMS at each speaker. If you have your amplifier on maximum gain it may blow your speakers, not because they are overpowered but because you might run into "clipping" issues running the amp at maximum capacity. Just to be safe I would dial the amp's gain down to 3/4 of the way to full gain. That should give you ample power and keep your amp from clipping and running hot.
Not sure about getting a better view but I suspect that you have more problems than just replacing the resistors. Like what caused the resistors to burn?
NEVER mix different power amps. Depending on the ohms of your subs, sell one of the amps, up to you. The 4001 has more power, but either amp will do the job, the amp needs to see a 1 ohm load, so your subs have to be dual 2 ohms, or single 4 ohms to do this. If your subs are dual 4 ohms then you will have to run your amp at 2 ohms which would be have the power, or a half an ohm, (Not Recomended) and be at double the power. You may be able to do a competion sound off and just "Burp" the subs, but at a half an ohm, dont expect to listen to it to long before it goes into protect and shuts down.
This problem is caused by one or more of your output devices (FET, Transistor, or IC) is shorted and causing the power rail to be connect through your speaker. Your amp boosts the 12v supply to a much higher +/- voltage rail which powers the amp's outputs. When the amp is shorted or overheated to a point of destruction you can end up with this problem.
It will need to be repaired by a technician.
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. Double check all connections. GOOD LUCK. A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.
