Hello, after the original loudspeakers of my Passat 3B are not so great, I want to install new ones in the front doors and move the old ones into the rear doors. I got loudspeakers from Ebay. Well it’s “only” Blaupunkt (normal price about 100 Euro) but they are brand new and better than the originals they should hopefully be. I also got the matching mounting rings for the 165 bass midrange drivers. Happy mutes I installed everything on Saturday, And this morning the test: an acoustic disaster. No rich sound, rather middle-loaded with tinned middles. Hard to describe. Anyway much worse than the original VW speakers. What am I doing wrong? How can I improve it without too much effort? Wouldn’t like to go back to the original speakers… sigh…. Servus
