Due to repeated requests, we will be developing and releasing an OEM-look enclosure for the E82. Next week we will use this thread for pictures of the sample as it's created, and then it goes off to the toolmakers. There will be a delay of a few weeks - maybe a month - to have units ready to ship.
It will look stock, it will be absolutely correct for the woofers we use in it, it will come with a grille that also looks OEM, it will mount cleanly and securely with no screw holes, and it will be up for preorder in several configurations and packages. We deliver a working system that's guaranteed to work wonderfully with your BMW, and the audio system in it.
(Note - if you have base Stereo, you don't just need a subwoofer. If you have HiFi, I feel the same way - you have other problems - but we have HiFi upgrades available with just the sub and with full systems).
If you are interested in being in on the pre-order, PLEASE email us. PMs get lot or we don't get notifications right away. Tell us your MY, if you have base Stereo or HiFi or Top HiFi (if you're not sure, check
here) and if you have Sirius SAT radio, thanks.
