Adapter rings turned up for the rear panels! & turned out to be a perfect fit this time!
cut down the original Audi screw mounts with the dremmel for closer fit lucky it worked one had already snapped off in a garage incident so I had seen the hole runs right down if not was going to pilot the holes, rings are 12mm thick! 200mm exterior &145mm interior diameter made up some looms from the JL650s to gold plated banana plugs for quick release in case future adjustments are required probably will lol! Some stainless steel self tapers for the speaker mounting countersunk the screws in the original holes for a better fit. Used marine-grade silicone sealant to completely seal the rings to the existing plastic mounts left to dry overnight, meanwhile I bolted the crossovers towards the rear of the panel having checked the position with the panel they just about fitted and screwed the female banana socket onto some foam neoprene in case or vibrations etc also plugs were hard to remove when flush to the panel made some small looms for these! I have put some 8oz wadding in the void as to experiment with the sound dampening. So far so good went to do a preliminary install today all going well a very tight fit indeed I think it will all just about work out once fully assembled so off I drove with the panels partially on then suddenly beep ****** airbag warning on so for safety sake about turn and back to base for a scan turns out I had knocked the drivers' side seatbelt tensioner off so removed panel to investigate further another plastic clip came away from the panel so into the garage with some gorilla glue to refix try again tomorrow I
