Custom Subwoofer Enclosure and Amp Installed

[Mouse]

I had this box and it indeed sounded much better(than BMW stock "subs"). It is a VERY tight fit. So much I had to repair/modify my gas door actuator lock. I ended up replacing with the JL audio stealth box I was lucky enough to acquire later on that fit better. This fills the mid/low frequencies well, but misses the solid hits/thump from a larger sub box. Sub selection will also play factor. I'm using a Kicker Comp RT shallow mount which I would qualify as entry/mid level. I'm sure you could drop some cash on a better sub for even better sound. Just be sure to get proper measurements as this box will limit your sub selection.

thanks Mouse. I'll stick with the current set-up I have since that sub hits HARD, like Mike Tyson hard. I will just continue to live with the box in trunk.

EDIT: I made my own homemade box by modifying the factory box. removed both 6" speakers and cut off face to install MDF and 10" shallow mount and its incredible! SO HAPPY to have a full trunk space again and sub sounds about 80% as good as other 10" sub in external sub (which was over kill)

I cant imagine too much air flowing out of the spare tire well on an E53 (or anything that isn't a Dodge product). Whether load floor or not, the floor is made specifically to add support to the rear shelf for hauling and insulation from road noise way down there in the Bimmer nethers.

My 1st hand (ear) experience (ear-perience?) is with my own JBL Stealth box and a JL 500w amp. I've run it now for 3 or 4 years (maybe more?). I do use Focal's in the doors, so I have pretty decent quality there. They run off of a JL VX 800 which does a fine job as well.

Thanks I might consider something like this.
I thought that oem plastic is not the best for subs vs these enclosures:

The reason I considered an sub in the trunk is because of all the rave reviews. But maybe it won't work well in E53

What I did for adding a sub to my non-DSP E53 was to source an OE subwoofer enclosure from eBay and mount it into the OE location. It took a little bit of rewiring and termination work to go from this:



to this:



and connected that up to my separate amp that is located in the spare tire well



To my ears this has been an excellent subwoofer sound added right where the OE placement was located.

fair. I have no experience with that box, but I do love the option of it and most swear they sound great. I have zero concerns with my plastic box but I'm not going to try to talk you into something you dont want but never hurts to listen to my set up so that when you buy the wood box, you can see how much different it could sound.
If ever intersted, just private message me. No worries!
