check the ohm load on the speaker. it may be too low for the amp... either that or you need a bigger amp for what you're trying to do. turn down the gain if you want the amp to last...

check wiring, check for liquid going to wherever your amp is located, read the print on your woofer and amp box...Type-R's are not 1500watts even in it's own dreams.

what deck do you have? try to keep the signal input into the amp as high as possible. this will allow you to turn down the gain on the amp. when the gain is really high up it is easier to cause distortion.

that amp should work fine with a type-r. you dont have bad luck. you just need someone to tune it correctly for you. turning all the ***** on the amp all the way doesnt make it "sound best". lol. i heard that excuse before.

the reason I think I blew the sub, is because I made holes in the box it souned like poop w/o the holes so i thought the holes would help. lol i got a much better box no need for holes and imo and my friends opinions are that it sounds fantastic

Making holes in the box is not the correct way to build a ported enclosure. For future reference, here is the proper way to determine the port size and length for the tuning frequency that you choose - link.

Your "holes in the box" method probably tuned the box way too high. When you play material below the enclosure's tuning frequency, the driver unloads. You can easily push it past its mechanical limits with very little power.
