OK guys, I know I'm kinda doing this backward but, I got a good deal on a US Amps DE-1000. It's 1000RMS at 2 ohms stable. I was going to get two of these but that would require two alternators. I'm not getting into this that far. Do I go with 1 big sub that requires 1k, or 2 smaller subs at 500 to 600k? I guess 3 or 4 10's maybe, if ohms and watts work out. Open to all combinations. Thanks
