Price lowered ! I had this in my 2008 328i sedan and it fit very nice and looked and sounded great. It’s for a 10” subwoofer, made out of fiberglass and is completely 100 % sealed. Standard mounting depth is 6”. I can only vouch it fit in my E90 sedan so not sure if it would fit in a couple. $110 including shipping ! Message me if interested. Thanks !!!!
