Slammed...I don't have a E93 but did have a E46 M3 Vert and installed the BSW system. It replaced the stock small sub that is placed where the winter package door to the trunk went & this set-up sounded SO good!!!
I wonder if BSW has done a similar set-up for the new E93s? The Upgrade for the E46 M3 was like around $1100 total for sub, amp & replacement speakers.
