Hello, have replaced the existing Axton stuff with a Rainbow CSX 265…doors are insulated and so on. What am I surprised about… what do I have for door boards?? The installation at the moment doesn’t make any sense, does it? I mean that everything is open on the side, so I can reach the speakers from behind! How can I get that? Actually, the speaker should use the volume of the door, or not? It’s basically now there like a free-air… I don’t see any other door boards that are open to the speaker sideways. Is there anyone who has them inside and closed them?Here’s a picture….
