E60 MB Quartz Under Seat Subwoofer direct replacement
 

I bought these from a member on here a while back but decided to go a different direction with mods. These are great and simple upgrade to the OEM subs. These are made specific for Bmw and will bolt on OEM speaker mounts. I'd say they are plug and play, but you do have to cut/splice OEM +\- cables.

The speakers have to been used. First owner sold car before installing and I only tested them to make sure they worked but did not leave them in.

Only looking to recoup my investment. $150 + shipping/PayPal fees.
