hi everyone. new here and would like to say hello to all! I'm having trouble running a orion 225 hcca digital reference series amp in 1 ohm mono. It's blowed 2 60 amp fuses each time I tried to use it. any ideas what may be the problem? I have 2 12" dvc 4 ohm subs wired parallel to it and it just pops the fuses when the bass hits. thinking about trying some 80 amp fuses and if that doesn't work, I guess I need to send it off and get it dyno tested. thanks guys, David
