SUB STOPPED WORKING!!!, AGAIN!!! Options

[acenova]

Alright, I'm irritated. This is the second sub I've gone through, the exact same kind as my last one to. I was just driving down the road listening to Lloyd Banks-on Fire and all of a sudden the base dissapears. Now, when I stopped the car, I checked the amp, and the amp was still on so obviously my sub blew or over heated. I highly doubt the sub blew because that sub can take quite a beating and is pretty Powerful. It's a MTX Thunder 8000 12". IF someone knows more about it and disagrees, please lemme know so I can beat someone up. But seriously, I think it's underpowered, making it over heat but I'm not sure because the amp is pretty powerful as well and should be able to power it just fine. Do you guys know if high heat, like outside temperature, can possibly mess up the sub? Personally I'd think that any heat would affect the amp before the sub but I could be wrong. My amp is fine, but my sub is messed, hopefully you guys can help me out w/ this one because this is the second one I've gone through.

Its actually not my opinion, as I've never dealt with an MTX sub (except for hearing them and not being impressed). It's just the general consensus I ran into on the net when I was researching for my subs. People would say: Whatever you get, dont buy sony or MTX etc etc... so.. I dunno.
