It keeps blowing a fuse

Generally, if you are using the manufactures fuse rating you can use a slightly higher rating and it will resolve the blowing fuses. Fuses supply resistance, if there isn't enough resistance you'll fry the system board in the amplifier. But if you have 25 amp fuses installed, install 30 amp, if you have 30 install 35 amp, 35 install 40. Anything higher will damage the amp.

Hope this helps.

A rare chance, something may be internally wrong with the amp and shorting it out which will blow the fuse.

Use the incorrect wiring of subs to the amp, you'll blow fuses and damage the amp from it turning off consistently. The amp should be running at 2 ohm stereo stable or 4 ohm mono stable.

Very few amps are designed to run at 1 ohm or less. Not to mention the subs can't handle it.

Bridging a f15d mono block from solid audio witch outputs do i use

Normally right positive and left neg. Your amp should have indicators on the terminals. Of the four you should have a separate + and - for each channel. This tells you which channel is for pos, and which is for neg. If no markings switch for each one left pos/right neg or right pos/left neg. It will only work on one way.

    I do not hear any music through my 10" M Audio Subs (M Audio Sound System)

    If you know how to use a multimeter, you can test the amp this way:

    -unhook the subs
    -hook up a cheapie speaker you know for sure works to one of the channels
    -unhook the audio inputs
    -turn the amp on
    -set your meter to VDC
    -put the positive probe on the inside of the input connector, being sure you make contact with th inner contact
    -take the negative probe and tap it on the outside of the connector

    What you are doing is sending a low voltage (replicating an audio signal) into the amp audio circuit and allowing the amp to amplify it. If the amp makes the speaker pop each time you strike the probe, the amp is working.

    You mentioned you need a 4 channel amplifier make the two, dual voice coil subs operate. The is not true and by hooking them up like that, there's a chance of damaging the subs. The reason is that the dual voice coils are interwoven and they have to get electrically identical signals or they fight against each other. The can mechanically fail, then, electrically fail, then even damage the amp too.

    Lost Right Rear Channel

    These are very complex amps that mainly use surface mount components. This amp has 4 vertical boards for the individual channels. It's difficult to work between boards and it's easy to damage the main board if you don't have good quality equipment to desolder them. If you want to learn to repair audio equipment, this is not a good starter amp. I'd suggest sending it to JL or a reputable local shop. If you're lucky, it could simply be a case of a dirty contact on a switch or a switch that's not set correctly. Try moving all of the controls and switches before sending it off for service.

    Can it Be Fixed

    Nothing should have been damaged. I would assume the speaker output shorted in one way or another...did you have a speaker hooked up? You most likely blew the output transistors and they ALL need to be replaced as one going bad will kill the rest since they're so sensitive. At least the PSU, seemingly, wasn't damaged. Contact, ask for Jason, he's excellent at repairing amps and has great pricing.
