Subs and amp shut off

[miniSPLlancer]

Ok, I bought 2 hdc310's, built a box 1.5 per net tuned to 35hz. Sounds great but then the amp goes into protect when I turn the volume up playing lows songs. I did nothing to the amp and when I had the sundowns sa-12's in I never had a problem even at 28hz. Now I've only had these subs for a couple days now so I haven't even remotely turned it up. I play my deck at 30, the loudest I've had it so far is 15 and that's when the amp goes into protect. The amp is a Cresdendo bc2000. These subs were stiff as hell at first but there starting to loosen up a little. With them being so stiff and not being fully broken in when I turn up the deck could that cause my amp to go into protect? I'm just looking for the reason why?

Just buy asking these questions you have solved my question, this is the first time I've ever had subs that were not dual 4's. They're are actually dual 1's lol. So basically I'm running my poor amp at .25 ohm with basically stock electrical because Mechman still have my alt. problem solved, thanks guys
