That jackhammer on pimp my ride had no real enclosure, That DB meter was bullsh*t, and thats a pure SPL sub, so their is a 10 out of 10 chance it will sound like crap but most pure $1000 and up SPL sub so. If You walled of that car and ported that sh*t and tuned that box high like in the mid 40'shz that sub will probably hit in the mid 150's with only half its recommened power handling. Im no MTX fan but thats the best large woofer i've seen to date,
