I have a 2000 Saturn LS2, and it came with a Factory 6.5" Subwoofer that was installed on the rear deck of the car.

Keeping in mind that this particular rear deck was specifically designed to house a subwoofer, and that in this case, the trunk becomes the enclosure. Pim was asking about putting woofers in the doors. I stand by my original statement that doors are not proper enclosures for subwoofers (but are fine for mids and highs).

I guess you could do some custom work on the doors to turn them into suitable enclosures. That would be an interesting project...
