the light stays on because the amp is still storing power. it only turns off when the capacitors on the inside have drained off all the extra power

Get a speakers to line input adapter and that will do the trick.

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.

First check your fuse by the battery then on the amp, if they are good then try another speaker

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?

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.

what do mean by "Those"?

any dc voltage at amp output is a sign this is blown. the problem is on the output transistors and can only be fixed by a technician

this link has install sheets just match the model number of you amp to the list of mtx amplifiers to find appropriate wiring diagram http://www.mitekasia.com/support/Default.aspx?sid=257&aid=2

Broken or loose PTO belt, or PTO shifter linkage.

you need the resisitor, it keeps the machine from basically frying up in case of a power surge.,
