when i ordered this sub i figured that it would be great, once the installation was complete, they sounded great, they are for sure not gonna hold 1150 RMS. wayyy over rated. they got hot on me alot and i was only pushing 450 watts to each one. after about 2 weeks of playing them, they finally started smoking really bad and burnt them. the warranty replaced them but the next set did the exact same thing. looking at the price, i should of known that it wasnt worth it.
