[QUOTE="R@kshasa, post: 8845656, member: 689097"] Replacing it would be ideal, as the subs can take 750-800 in a good sealed box (which I have). I'm also not a fan of the 9701's lack of a sub-sonic filter, considering they are 10" subs. Even with the X-over at 80, it still happens. I believe it's probably a setting on my head unit, just haven't had a chance to test it yet. I have bass boost off, but I read that there's a setting in the EQ menu that adds +3db to 62.5hz, on top of the EQ setting. If that's the case, the amp would try to produce about 2x what it should at that frequency, resulting in protect. I'll update when I test it. My last resort will be to borrow my buddy's spectrum analyzer and put it on the pre-out and amp outs to see if there are anomalous spikes. [/QUOTE]
