Up for sale is a single used JL Audio 10IB4 10 inch free-air subwoofer, mounted on a custom MDF board designed to fit the trunk of the BMW e46 3-series.

The subwoofer was purchased from Tweeter in Boston 11/16/00 and has seen light use in my 1999 323i. This is an "infinite baffle" application, requiring no enclosure. Specifications, taken from JL Audio, are as follows:

Fs (free air resonance) 37.5 Hz
Efficiency (1W/1m) 89.0 dB
Znom (nominal impedance) 8 ohms
Pt (continuous thermal power handling) 100 Watts

See link for further details:

The mounting board measures 42.3" by 18.5" and was custom fabricated from 1" MDF and covered with gray carpet to match the trunk. The sub fires through the ski pass. It fits perfectly and was designed to take up almost no trunk space; it uses one inch of trunk depth and the speaker with magnet protrudes an additional 5 inches.

The setup will fit any e46 (99-current) sedan, with or without folding seats. It may fit e46 coupes as well; buyer responsible for fitment.

The subwoofer produces powerful, clean bass when paired with a properly powered amp. This sub will not rattle your teeth or the neighbors' windows; it is intended to provide tight bass to augment your choice of music.

The subwoofer is used and in good condition. It is not blown. The MDF board itself is undamaged and the carpeting is clean. Three feet of heavy gauge speaker wire are included. I am selling because I have sold my car.

This item will be listed on eBay starting Tuesday, 9/21/04 at 5 PM. Here's the link:

Further pictures are available at:

Item will be shipped promptly via UPS or USPS upon receipt of payment by Paypal, money order, or cashier's check. Alternatively, the subwoofer may be picked up in Southern New Hampshire. Email me with any questions or for a shipping estimate.

Asking price is $150; offers to be considered after the eBay auction ends if the item remains unsold.

Thank you for your interest.
