I will be taking my car to audio x in about a week. I have decided to purchase two C fours for the build so I am selling my A4’s. One of the A4’s has a brand new plexi. It’s in great condition. The other one is in Perfect working condition but has a few scuffs on the plexi as well as a small ding in the heatsink. I purchased the one with the ding from Doug Dobson and he sent me a new heatsink if I felt like changing it out. I’ve decided just to discount the price of that one in stead. Zero functioning problems. I have ran them both for over a month and they sound incredible . Just as an FYI,I have reached out to nick and he can make new covers for them if that’s something that you would be interested in. $450 for the one with new plexi. $350 for the other one. Lowball offers will be ignored. Respectful offers welcome. I will entertain taking on shipping cost depending on locations.
