Rockville W15K6D2 V2 15" 4000w Peak Car Audio Subwoofer Dual 2-Ohm Sub 1000w .... Used by me for probably 20 hours, bought brand new in 2022 and has been stored inside since removal from car. Now have an 18 inch edge sub so not needed. Can post but very heavy. Perfect working order and very loud, I had this in a 5 cu ft ported box.
