is my treo blown?

[acold7dusta 10+ year member]

well heres the setup: memphis ST-1000D (1100 RMS @1) powering one Treo 10" SSi D2 sub (750 RMS) in a 1.8 cu ft sealed enclosure @ 1 ohm. Alright so i set my gains to around 3/4 and i dk why but the memphis amp doesnt get very loud at all (ive tried many things) its sounds amazing, just not as punchy as i thought (at all). anyways i was blasting music the other day, and after about 20 minutes, sub stopped playin. i pull over and check everything, and the amps "fuse fault" was lit up. so i order some new fuses. and BTW local audio store put in 2 30 amp fuses instead of the 40s that are recommended. so i blew both 30s and waited for the new fuses to come in. got the fuses today, and put them in today. Power the sub up and it makes like a rattling noise inside whenever the bass hits:crap: . after a few choice words, i remount my amp, turn the gains down to about 1/2 and put the seats up. you cant really hear it rattling nemore. What exactly happened to my sub, and can i fix it in anyway? this really upset me, since the same thing happened to my old kenwood sub, and i only have had this stuff for about a month

please help me //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif

box is way too big for a single 10" sealed and ssi's prefer to be ported in my experience anyways.

Set your gains correctly, first of all.

To see if your sub is blown, check the coils with a DMM.
