i have a custom box for a 92 325i which will probably fit most bmws. i am in the process of finding out. the box contains 2 10" mtx subs that hit pretty hard. i also have a single 12" sub in a box and last but not least i have a 600 watt amp by legacy that has a remote bass boost control. all items are used but all work very well. oh i also have a box with 2 12" mtx subs that i would be willing to let go for the right price. so email me and make me an offer. xrt52@yahoo.com
