its great but i dont have a working sub at the time, mine blew with in 24 hours of installing it, it was either a bad sub ( thats what the shop says ) or the shop turing the gain up all the way blew it ( prob clipped and smoked the sub ). but the box was in great shape, i love it, and the sound deadening was great as well, deff helped with the rattles for the small amount of time i had the sub working.
