is a type-r more durable than most??

I would consider a more powerful and better quality amp since you blew the 600rms Infinity subs with the same amp. Sounds like you drove the Xplod amp into clipping trying to make it louder. The Type-R's handle at least 1500rms of clean power. Which amp is it?

the black 1,000 watt one ''the rectangle''

oh yea .......one more ''Q'' would 4 cu ft. be okay for a type-r 12''?????
