Well here it is. A freind got a new 18inch btl, and he was throughing out his 10. I figure, since I have some left over LN from a computer cool, I would design a box and have LN cooling the sub. Yes this will involve some major work on modifying the sub. This ever been done ?, I just want to run 8000rms to it. And not have er burn. This is my first post aswell, and ill be ordering some subs later on . I figure if I vaporize the LN and have blowing through the sub, that it atleast not kill it for 10 seconds of playing. Crazy or worth a experiment ?
