Man I had the same problem, as soon as i touch the power wire to the amp, with the ground already connected, I get an instant pop. But i ended up puttin the ground wire in the power term, and the power in the ground term, durrrrrrrrrrrrrrrrrrrr. But fixed it and it worked. And I also had a prob with a audio cough shitty cough cough bahn amp. I had 2 10s that wanted more power than it could put out, but I had gains all the way up, and music blastin, The fuse would sometimes needed to be jiggled to make it work, then I was drivin, the fuse poped, but I wiggled it and it still worked even though the fuse was popped, then I was drivin and I smell really bad burnt plastic, and the fuse melted itself to the amp and It yet still worked with being wiggled at times. Maybe your just puttin alota stress on your amp, put the gains down a lil, try 30 amp fuses, 20s blow easily. And check to see if your power is in the right place, and your ground is too, dont make the same mistake that I did
