servus people, I have my audi now a year and think about now to build in a small system so back 2 boxes on the shelf and still a final stage in the trunk pure without subwoofer! Is it worth it and who can recommend me something good and relatively cheap is important to me just a good sound and nice loud ! you know how ́s :P! Oh and is it worth building in the car system at all xD! 80000km I have it first ! for many quick answers I am happy ! mfg NO Kky THANK YOU!
