It is a possibility. I would like to wait a week from my original post to see if I can sell it as a whole piece. If it doesn't sell as a whole, then I will contact you about the price of the brackets.
check out ebaymotors.com under manuals and literature. sometimes they have the actual service manuals used by the dealers. read the auction carefully because some are the actual binders and the others are cd's of the scanned pages.
I am looking for the Mazdaspeed Protege subwoofer enclosure that fits under the rear deck with the mounting hardware. I don't want the speaker or the amp. I figure maybe someone would have one sitting around after they upgraded their system.
