blown or just exceeding limitations?

I was adjusting my amp trying to get the setting tuned in a lil better when on one of my subs I heard a mild thump/pop on the lower notes. One sub made the noise each time and the other sub never did.. I backed the gain off a tad and it stopped.. Sub still sounds good and hits hard.. Never smelt anything or seen any smoke coming out the port.. Ideas? If it was clipping wouldn't both subs have done it?

Sound like the subs were bottoming out.. subs can't handle the power from the amp

You have a ported box right? DO you have a subsonic filter on your amp? If so you need to turn it on

Yes. I do have a subsonic filter.. It's on set approx 32hz atm.. I'm still toying around and will be adjusting more tomorrow...

The 1st sentence I can understand however w/o info, how can you tell that his subs can't handle the power w/o more info needed?

ANY sub can be handled by an amp....it's the owner/user that should know how to hook it up properly, set gains correctly, fine tune it, etc.

Set your subsonic filter around 25hz
