Re: time to replace subs.
First, I would recommend you learn to set your amplifier correctly. Your subs were most likely blown due to excessive heat caused by clipping. Second, that audiobahn amp most likely doesn't even make rated power. The reason you think its so powerful is most likely because of the gain being set incorrectly and being drove in to clipping.
But to answer your original question... a pair of Sundown Audio SA10s fit your requirements.
