Every time, whenever I put in the 20A fuse it sparked, which I figured was slightly normal, a little weird since the car wasnt on and the PC wasnt on, but normal. Then the 15A in the M2 would blow. Remember the car was off the entire time. Did I do something wrong? Is it a problem with my ground? My amp works fine (it runs off the same positive from the battery, connects to the distro block) so Im guessing its not the power wire, but I dont know. I would say its definetly not the REM wire (right?). So maybe its a problem with the ground. Its grounded where all the other things are grounded (2 amps). Maybe the wire is too long, but even so would that make sense? What is trying to pull power when the PC is off? I dont get it.
Please describe the wiring and which fuses are popping? Perhaps a basic paint drawing would help.
From what I got so far, you have a large cable from the battery to the trunk distro block. You have a 20 amp fuse there. Then, from the distro, you have some wiring to the M2 and your amp. The fuse on the M2 is blowing, even before it is on, while the amp continues to work with out a problem. Is the 20 amp fuse in the distro popping?
Sound like there is an issue with the M2 wiring. I doubt it is a ground issue. Remember what I said earlier, fuses pop when you EXCEED the current rating, either because the fuse is too low a value for the item being powerd (not likely since you haven't even turned the PS on) or because THERE IS A SHORT. You need to check to make sure you have the M2 connected properly. I know that the M2 has solder point on the bottom of the board. MAKE SURE THEY ARE NOT TOUCHING METAL OR SOMETHING CONDUCTIVE. What do you have under the M2? Try and slip a piece of paper between the M2 board and what ever is under it. Does the paper fit between? Check to see if something might be making contact with the M2 that shouldn't be. Also, the M2 doesn't have a molex, but just connectors that accept the female quick disconnects with wire attached. ARE YOU SURE THAT YOU HAVE POSITIVE AND NEGATIVE going to the appropriate connectors??? Quadruple check.
Disconnect the M2 from the mother board, and see if it blows the fuse when you insert the 20 amp fuse. If not, then it has to do with the MB. Is the MB youching metal? Try and slip the paper inbetweent he MB and what is under it. Look for anything making contact with the MB that shouldn't be making contact.
If you find nothing wrong, DISCONNECT the wires from the disto to the M2 at the M2 end, insert the 20 amp fuse, and see what happens. There HAS to be a problem in that "leg" of the wiring. Something is wrong between the Distro Block and the M2, or, something is shorted in the M2.
Good luck, and report back.
