ur prolly crankin the gains like a muther f'er to make that sub sound decent on that amp. Turn them down....
This is why people say "Underpowering a sub can blow it" because people turn the gains up to make it sound decently loud and send it hella distortion causing a sub to blow. Get a bigger amp or turn the gains down....besides I hope you have warrenty on that Type R cuz they arent the most durable subs out haha (i know many people who can go for that)
