I have here a pair of rear shelf supports that were fitted to Top Hi-Fi/Logic 7 cars. They are different to the standard base audio cars in that they allow for the fitment of tweeters and have raised sculpted grilles rather that the low-rent standard items. See this link for a comparison:

They do NOT however come fitted with speakers. Ideal for Logic 7 upgrades or other upgraded component speakers such as Focal etc.
PM me with offers, not looking for a fortune for these, just no use to me as i own an E90.
