I have a 2009 E90 Sedan. I'm looking for a custom fiberglass sub box that fits in either the driver or passenger side back corner of the trunk for a 12" sub.
I don't need a the actual subwoofer or amp.
However if someone happens to have this box with an IDMAX 12" dual 4 ohm sub in good working condition I'll pay more $$$ to buy that too
