yeah this sub is insane just liek sam jones said cant beat them. i had 2 in a cutout in my 98 silverado extended cab and i would set off car alarms like no other. These subs would make the ground quake when you would stand there. I once drove by one of my friedns house and now i owe him repair bills cuz his house fell apart literally!!
