I'm about to get these http://www.caraudiodirect.co.uk/product_...7a717393a4dc213 or anything in the price range (budget £50) for the front doors for my A4 Avant 96 P reg. My worry is if they fit with only using adaptors and no modding? The mounting depth of the above is 64mm. These will be powered by my Alpine head unit so not going to be amped. Thanks.
