Subwoofer for X5 E70 with 3rd row seating?
Hey guys,
I'm planning to upgrade my base/Stereo Audio system and add a Subwoofer too.
The problem is I have the 3rd row seating so I cannot use the JL Audio Stealthbox.
Did anybody built something custom? I'm wondering if the space next to the battery can be used. (see the picture)
